Virtual Testing of Composite Pressure Vessels

Virtual Testing of Composite Pressure Vessels Virtual Testing of Composite Pressure Vessels Composite pressure vessels generally perform better and last longer than traditional metallic pressure vessels. They are also more corrosion-resistant and can withstand higher pressuresfor example, hydrogen needs to be pressurized to 70 MPa to achieve minimum vehicle autonomy requirementssomething that is difficult to achieve with metal.There are a number of restrictions on size, weight, efficiency, and physical reliability of hydrogen storage devices for the automotive industry. At these smaller dimensions hydrogen needs to be stored at very high pressure in order to be energy efficient, which in turn requires a very strong and fatigue-resistant container, such as a carbon fiber-reinforced composite pressure vessel.Although stronger than metal, carbon-reinforced composites still fail. This usually starts at a microstructural level, such as fiber breaking or matrix cracking. It can also be rel ated to variances in microstructural design elements, such as fiber orientation and fiber volume fraction, which also have great impact on overall structural performance.Fiber AlignmentIn structures made of composite materials, damage actually starts at a very small scale compared to the size of the structure itself, says Leandro Castro, co-founder of MultiMech Research and Development, a provider of advanced computational tools for evaluating complex engineering challenges. For example, in carbon fiber composites, debonding, another important type of damage in composites, can occur between the fibers and the resin surrounding them, where each carbon fiber is about 0.0050.010 millimeters in diameter.Fiber alignment in the composite material is also important. If fibers are aligned parallel to the load direction, then the overall composite failure is controlled by the failure of the fibers, which have very high strength. If the fibers are aligned perpendicularly to the applied load, then the failure of the composite is dominated by the matrix, as well as the interface between matrix and fiber, which is much weaker than the fiber.Created by MultiMech, MicroMech is the industrys fruchtwein realistic microstructure reproducer. It is capable of virtually creating a wide range of microstructural types, such as fiber and particulate composites.Image source Multimechrd.comDesigners and engineers strive to accurately predict the physical reliability of materials and their microstructures before production starts. This requires sophisticated software and algorithms. For example, MultiMech RD provides two-way coupled multi-scale mechanics software that can evaluate events happening at multiple scales simultaneously using multi-scale algorithms for both impact and quasi-static problems, including explicit crack modeling. This sort of approach allows the design kollektiv to build virtually any material from the ground up (fibers and resin) and accurately simulate the physi cal reliability of the designed structure, before the first physical prototype is ever made.This allows engineers to control microstructural design variables, such as fiber orientation, volume fraction, type of fiber and matrix, and assess the effect of each design variable on the overall structural performance of the component by using its unique two-way coupled multi-scale solver, says Flavio Souza, also co-founder of MultiMech RD. The software can generate microstructures automatically to expedite simulation pre-requisites. It can automatically create microstructures of existing or novel materials so engineers have the most freedom of design by virtual testing combined or new materials before they are ever manufactured. In such cases, engineers can get a feeling for the mechanical response of combined resin/fibers and actually design the material to meet their design specifications.Optimizing Design When designing composite pressure vessels engineers must determineThe most approp riate fiber and resin matrixHow many layers/plies are neededFiber orientation in each layer/plyThe level of damage (microcracks) the composite can withstand.These questions are mostly related to defining parameters to maximize the stiffness, strength, fatigue resistance, and long-term performance of the composite pressure vessel. Due to either service loading or manufacturing defects, virtually all composite structures exhibit microcracks, says Souza. Each microcrack may or may not propagate during service life and new microcracks may be initiated when the composite is subject to thermo-mechanical loading.Predicting failure is extremely complicated from the engineering viewpoint because even though carbon fibers can be considered an elastic material, the surrounding matrix is mostly a thermo-viscoelastic material.While the fibers carry most of the load of carbon fiber composites, loaded in the fiber direction, their long-term behavior and failure arecontrolled by the viscoelastic (t ime-dependent) properties of the matrix surrounding those fibers, Castro points out. The material will also have intrinsic statistical variations due to manufacturing. Carbon fibers are relatively expensive and can account for most of the cost of a composite pressure vessel, so they need to be used wisely. Our two-way coupled multi-scale mechanics software has capabilities for modeling damage evolution in composites, which is essential when optimizing the design of composite pressure vessels.fruchtmark Crawford is an independent writer.The software can generate microstructures automatically to expedite simulation pre-requisites.Flavio Souza, co-founder, MultiMech R&D

Why the Fight for Paternity Leave Is So Important

Why the Fight for Paternity Leave Is So ImportantWhy the Fight for Paternity Leave Is So ImportantIm Fighting for Paternity Leave - So Should YouFighting gender inequality in the workplace includes letting fathers to be fathers.Earlier this month at Women Deliver, one of the worlds largest conferences on gender equality and womens rights, I was part of a kollektiv that made an announcement. The topic paternity leave.To some, that may seem surprising. Why talk about dads at a conference for women? The answer is simple. Supporting men as caregivers is a necessity for gender equality.In the not-too-distant past, businesses were built on a Mad Men model. The presumption was that women will stay home and do all the caregiving, while men stay at work. That way of thinking helps explain why the United States still has no national paid maternity leave. The thought process behind it is that the man will make the money, while the woman stays home. (For more on this, see my opening remarks at a U.N. event.)Unfortunately, the structures that keep those old ways in place, including workplace policies and cultures, still havent been rectified.Today, most businesses have some paid maternity leave, usually covered as disability leave following a birth. But despite some progress in recent years, only 29 percent of U.S. businesses offer paid paternity leave.And while unlike the United States, virtually all other countries offer some paid maternity leave, fewer than half offer any paid paternity leave.It gets worse. Even when paternity leave is available, numerous forces prevent men from being able to use it in its entirety.This brings us to the Women Deliver conference, which took place in Vancouver. Dove Men+Care a company I lebensabschnittsgefhrte with on this issue and Promundo released the State of the Worlds Fathers report, packed with data from interviews with more than 11,000 men and women. The findings show just how big a problem this is.The overwhelming majority (85 percent) of fathers across seven countries want more time at home to care for their new children. But paternity leave often pays only a fraction of what men make at work and after welcoming a new child, families are particularly strapped financially. Forty percent of parents say financial barriers are the biggest impediment to paternity leave.The stigmas against taking it are also powerful. Majorities of women and men say attitudes among colleagues and managers often leave dads feeling unable to take their paternity leave. This is a topic I covered in depth in my book, All In. Men have been fired, demoted, or lost job opportunities for taking paternity leave or requesting a flexible schedule.I explored this in the wake of my own battle for fair parental leave. When my wife was pregnant with our third child, we determined that Id be needed at home for caregiving after the birth. The policies I was under at CNN, part of Time Warner, allowed any parent 10 paid weeks after having a chi ld except a biological father who had his baby the old-fashioned way.I challenged this internally. After our daughter was born prematurely in an emergency and the company refused me the 10 paid weeks, I took legal action. Ultimately, the company revolutionized its policy, in a win-win for parents and for the company itself.Businesses benefit from making paternity leave a reality not just officially in policy, but through a culture of supporting men in taking the leave. Its proven to attract and retain employees and increase gender equality in an organization. After all, as long as men are prevented from caregiving roles, those responsibilities will fall more on the shoulders of women. Theyre pushed to stay home more, while men are pushed to stay at work more, and the sexist cycle continues.To help paternity leave become a norm at businesses everywhere, Dove Men+Care has partnered with Deloitte, Women Deliver and Promundo to create a Paternity Leave Global Task Force. Its aim is to identify and promote solutions that will result in improved access and uptake of paternity leave for all men.Announcing this plan at the conference, Women Deliver President and CEO Katja Iversen called the effort a no brainer. Alan Jope, CEO of Unilever (Dove Men+Cares parent company) said the commitment to paternity leave is so important because everybody wins moms win, dads win, and the kids win.Its time to put the Mad Men era behind us once and for all. For that to happen, businesses must embrace modern fatherhood. Todays dads are as committed to caregiving as moms are. Lets make sure they get a aussicht to be there, from day one.The fight for gender equality affects company culture.

How to Get the Most Out of Your Meetings

How to Get the Most Out of Your Meetings How to Get the Most Out of Your Meetings Gathering your team in one place to brainstorm new ideas or disseminate information seems like a good idea in theory.In practice, however, meetingsare often nothing more than a waste of time.Employees are easily distracted - and for good reason. They may be thinkingabout the work they had to put on hold while they sit at the table. If workers are staring blankly at walls or not-so-discretely checking their phones, the problem isnt their behavior - its your inability to hold their attention.As many as 38 percent of employees admit to daydreaming during meetings and conference calls, according to recent research conducted by Klaxoon.While some may argue companies simply have too darn many meetings for their own good, Klaxoons research suggests the culprits arent frequency or length. Rather, the key is simply running the meeting efficiently.Well-run, efficient meetings are certainly a boost to producti vity and are integral to the day-to-day of high-performing teams, says Matthieu Bucher, CEO of Klaxoon. They are a place where people share information and knowledge, build consensus, and make decisions.Oh No - Not Another MeetingIf your meetings are rarely productive, that can have a significant impact on employee happiness and productivity, especially in busy amtsstubes where every minute counts. Twenty-two percent of respondents to the Klaxoon survey reported that most of their office meetings were a waste of time.What makes these meetings wastes of time? Generally, Bucher says, its one of two factorsMeeting goals are never clearly established, leading to a lack of focus orfrequent digressions away from the most pressing topics.Participation is limited, and people are either not motivated to engage or feel they cant actively take part in the decision-making process.To combat this, every meeting should have a set agenda and a strong facilitator to keep things on topic and ensure no one individual dominates discussions, Bucher says. Activities such as quizzes and group brainstorms can also make meetings more successful. If every participant can easily share their ideas and have a say, you see a drastic change in team and meeting engagement.If your meeting gives workers any opportunity to check out,restassured they will do exactly that.One of the main distractors is the fact employees bring their own devices to meetings and will use these to ease boredom or fill the void if they do not feel included, Bucher notes.One easy way around this is to incorporate employees devices into the meetings. For example, you could designin-meeting activities that employees access via their mobile devices and laptops.The Benefits of CollaborationIf employees feel that their opinion isnt valued or that it isnt their place to speak up in a meeting, they will withdraw and focus on other things. The best way to get full participation is to create an environment where all participa nts truly have a voiceYour employees want to collaborate. In fact, 57 percent of the people surveyed by Klaxoon said collaboration is integral to their success at work. Among millennials, that figure is even higher at 64 percent. Its easy to turn meetings into productive, efficient uses of time when you actively include employees - because thats something they already want to be doing.Meetings that bring together diverse employee populations can also help to break down walls between departments, driving increased collaboration across the organization.Effective meetings help to break down silos, guaranteeing a fluid flow of bottom-up information that permeates throughout teams all across an organization, Bucher says. Collaborating efficiently in meetings just leads to great teamwork.Employees will be happier, more productive, and morefocused when they are asked to participate in meetings and other gatherings. Building a collaborative culture at your company is the first step toward meeting success.

53% of professionals work remotely at least half of the week

53% of professionals work remotely at least half of the week53% of professionals work remotely at least half of the weekCould it be that the employers are approaching a tipping point in embracing work flexibility? Thats the conclusion of a new global report that found some 53% of professionals work remotely at least half of the week - and increasingly, employers are embracing remote work and other flexible options.The report by International Workplace Group IWG, based on research gathered early in 2018, marked the 10th year that IWG has surveyed employers about flexible working. Titled The Workspace Revolution Reaching the Tipping Point, the report offered many pro-flexibility responses in the 70th and 80th percent rank or above, CEO Mark Dixon said. The answers, he noted, surprised even those of us at IWG who have worked in the industry for many years.The end of the fixed-site workplace?The IWG report seems to signal great news for job seekers looking for work flexibility. The fin dings are a clear indicator that the bell has tolled for traditional, fixed-office working, the report concluded. Namely, 70% of survey respondents said they worked outside of their employers primary offices at some point in the week. Some 53% said they work remotely at least half of the week.Arguing that mobile workers need supportive environments to work productively, the IWG report notes how workers are clamoring for mora choice of location while more and more businesses are actively moving to flexible premises instead of traditional offices.In assembling its report, IWG talked to more than 18,000 professionals in 96 countries, representing a range of businesses and industries.Why more professionals work remotely, and other findingsMore employers are responding to the growing demand from employees for drop-in locations where they can work outside of the main office, the study found. In response, 78% of respondents are offering flexible office space to accommodate employee demand .Here are some of the strategic and financial benefits of work-from-anywhere policies, according to survey respondentsIncreases employee productivity 91%Helps business grow 89%Keeps their company competitive 87%Boosts profitability 83%Attracts and retains top candidates 80%Mitigates risk 73%Helps navigate volatile markets 67%Being either location independent or offering multiple work locations helps their companies streamline operations and minimize hefty overheads, respondents said, meaning more agile growth initiatives and better risk management.This article first appeared on FlexJobs.

Hiring in 2012 The Year of the Video Interview

Hiring in 2012 The Year of the Video InterviewThe world might not have ended in 2012, but last year certainly welches an exciting time for the video interview. Employers discovered how helpful it could be to connect with top candidates via video and shorten their hiring process.With the tough economy and the war for talent, it was more important than ever before to make good hiring decisions in 2012. After all, a bad hire could set companies back as much as $50,000. No company wants to lose out on large sums of money or great talent with the ability to move their organization forward.This is where video interviewing comes in, allowing companies to get a more personal feel for candidates earlier than in the traditional hiring process.Here are some other ways the video interview helped employers in 2012Saved time One of the most essential ways the video interview helped employers last year was when it came to saving time. Time is obviously a valuable commodity for all companies, especi ally in the hiring process. When looking to hire the right people, most companies are looking to scoop up the top talent fast in order to fill positions and nab great workers before the competition.Video interviewing is a great way to save time in the process because scheduling a video interview is much easier than making time for an in-person sit down. Because one-way virtual interviews occur asynchronously, for instance, it becomes a snap to schedule them with even the busiest passive candidate. Employers merely pose their written questions and candidates answer on film in their one-way virtual interviews. These answers can then be viewed at any time.It should come as no surprise that a survey from the Aberdeen Group found employers could watch as many as ten one-way virtual interviews in the time it took to perform one phone interview. Thanks to the video interview, employers found a better solution to the time-consuming and ineffective phone interview while cutting down their ti me-to-hire in 2012.Allowed talent pools to grow In 2012, Spark Hire opened its doors to the world. By allowing the video interview to go international, Spark Hire helped employers and job binnenseekers from all over the world connect.For employers, this became a great way to start hiring outside the companys geographical area. No longer stuck with only the candidates in their own backyard, companies could expand their talent pools exponentially.This is important when you consider the raging war for talent and the ever-widening skills gap. Its important employers leave no stone left unturned when it comes to finding the right person for open positions. The best person for the job might be around the corner or on the other side of the world, and video interviewing makes these candidates equally easy to get in touch with.Saved money Found a great international candidate? Thanks to video interviewing, you no longer have to worry about footing a massive airline fee in order to see if the yre the right person for the job. Just schedule a live virtual interview with your top-tier talent and youll be connecting face-to-face in real time without anyone needing to buckle up for takeoff. Unsurprisingly, this allowed companies to save up to 67 percent of their hiring-related travel expenses in 2012.Got mobile In 2012 Spark Hire launched the first ever video interviewing mobile app. Now candidates can record their video resume or their answers to one-way virtual interviews on the go. Think one-way virtual interviews made scheduling an interview easy before? Now candidates can step into a quiet room, record their interview answers, and then go back to the rest of their day.With the increasing importance of mobile devices in our everyday life (even grandma is liking your Facebook statuses from her smartphone) it only makes sense to help the job search go mobile while maintaining the personal connection the video interview allows.To the future Video interviewing in 2013 With a ll the strides video interviewing has made in 2012, its not shocking to find out a recent survey showed six out of 10 employers are embracing video interviews in their hiring process.Looking forward to the rest of 2013, 13 percent of employers plan to utilize video interviews more frequently in their process. A further 85 percent plan to continue using video as an important component for hiring the best people.Companies are using video interviewing to connect with candidates on the go, save time and money, and grow their pool of talent to include the best and brightest from all over the world. We dont know what the future will hold for the video interview in 2013, but based on the experience of 2012 the new year looks brightHow will your company use the video interview to hire the best in 2013?
