Brentwood, TN, March 20, 2015 – VEXTEC Corporation co-founder Robert Tryon will be making two presentations at the 2015 Aircraft Airworthiness & Sustainment (AA&S) Conference. The conference will be held in Baltimore, Maryland March 30 – April 2. Representatives from the Air Force, Navy, NASA, Federal Aviation Administration and industry will be in attendance.

The first paper, “Probabilistic Software Tool to Predict Statistical Distribution of Stress Corrosion Crack Lifetimes” will demonstrate software, SCCrack, developed collaboratively by VEXTEC, University of Virginia and Navmar Applied Science Corporation. SCCrack predicts the statistical distribution of stress corrosion cracking (SCC) in cracked generic components fabricated from various materials [stress corrosion crack size vs. time and SCC life], in particular ultra-high strength steels such as AerMet100, 300M, and 5083 aluminum alloys. The necessary crack growth rate input data was obtained from an experimental effort as well as from the literature.  Random variables including the initial crack size and shape, applied polarization, applied degree of sensitization (when relevant), as well as material SCC rates are also considered.

The second paper, “Uncertainty Propagation in Multi-Disciplinary Computational Analysis” will discuss the uncertainty management analysis framework being developed for the US Air Force under the Airframe Digital Twin program. The analysis methodology, applied to an airframe canopy sill longeron, seeks to optimize computational and testing resources to drive robust predictions at the lowest cost. Uncertainty information is propagated through 3 key disciplines – aerodynamics (magnitude and time of application of the stick forces), structures (computation of the resultant stresses) and fatigue (combines stress input with material microstructural uncertainty). The presentation will also demonstrate how probabilistic virtual inspection can be incorporated in the analysis to predict a condition based maintenance forecast.

The Manufacturing Maintenance Balancing Act

In a 2006 Nielsen study1, auto industry manufacturing executives reported that stopped production costs averaged $22,000 per minute or $1.3 million per hour of downtime. When surveyed, 53% of the manufacturers agreed that predictive and preventative maintenance was the key to reducing this loss of productivity and revenue. So, what is the best practice for determining how to maintain and operate your manufacturing line to optimize productivity and maximize revenue?

Most engineers can agree that industrial equipment is designed to operate safely within a certain range of conditions, and in a perfect world, would be operated within its predetermined limits. But often, the designed-for conditions and actual operating conditions are worlds apart. This gap between “as designed” and “as operated” often ends with one or more of the following: premature failure, unanticipated downtime, unplanned maintenance, productivity losses, unexpected repair and replacement costs, and lost revenue.

VEXTEC Virtual Life Management TM (VLM) technology predicts the durability of manufactured products by aggregating all the various data sets that describe the product and its behavior. Traditional design analysis today accounts for some of these data, for instance, by looking at the stress imparted on a component. However, stress data alone, is not enough to predict durability which is a function of the materials reaction to that stress. This is what differentiates VLM from traditional methods. By relating all the data that describes the product in one computationally robust platform, VEXTEC VLM simulators give engineers the ability to see how material processing variation, design changes, or changes in the operating conditions affect component durability.

The manufacturer estimated that in this one project, VEXTEC saved them over $700,000 in capital investments.

How Missile Defense Technology Is Advancing Health Care

VLM helps bring safe and effective devices to the patient sooner.

VLM helps bring safe and effective devices to the patient sooner.

The intersection of engineering fields yields a fertile breeding ground for new ideas. The combination of previously separate concepts lies at the heart of creativity and novelty. An increasing amount of these technological breakthroughs generate innovations with commercial potential.

A recent report  released by the US Department of Defense’s Missile Defense Agency (MDA) entitled, “Healthy Innovation – Missile Defense Technologies Applied: Medical and Safety Solutions“, highlights how improvements in health care have been spawned in unexpected ways by missile defense technology development. Technologies developed by twenty different companies are highlighted. VEXTEC’s Virtual Life Management® (VLM®) technology has been identified as one such technology which has multi-disciplinary application. VLM improves product safety and reliability using computer simulation. The simulation software tools predict damage over time to help engineers build better products. The need for early prediction of product safety exists for many industries, from weapons systems to medical devices.

Several medical device companies such as Boston Scientific have used VLM to simulate bench testing of stents and electrical leads. The medical device market is a demanding commercial market since the reliability of an implanted device can be a life-or-death issue. VLM affords medical device makers the capability to make design decisions before extensive physical testing and prototyping. VLM helps companies reduce the time and cost of product development and certification while supporting the Food and Drug Administration (FDA) goals of getting effective and safe treatments to patients more quickly.

VEXTEC Founders to Attend 2014 Southern Automotive Conference

VEXTEC is attending the Southern Automotive Conference Oct. 9 – 10, 2014

Oct. 6, 2014BRENTWOOD, Tenn.VEXTEC’s Chief Technology Officer, Dr. Robert Tryon and Chief Product Development Office, Dr. Animesh Dey, will be attending the 2014 Southern Automotive Conference, October 9 – 10 at the Birmingham-Jefferson Convention Complex in Birmingham, Alabama

At the conference on Thursday Oct 9th at 2:15, a panel presentation will be hosted by ArcelorMittal and Kia on “The Innovation Imperative” to discuss a study that stressed the need to innovate close to the production lines to incorporate essential technologies faster. The Brookings Institute conducted a study in 2013 titled, “DRIVE! Moving Tennessee’s Automotive Sector Up the Value Chain” which discussed the need for the South to transform its automotive manufacturing base into an definitive “advanced industry.” One of the challenges identified in the study is insufficient private research & development (R&D) resources and shortage of collaborative technology development throughout the Southern auto supply chain. This panel will explore novel approaches to identifying technology needs and to improving the ability to innovate locally.

VEXTEC is a local company in Nashville, Tennessee that has received over $25 million in Federal R&D funding specifically for advancing the manufacturing production lines of durable goods. With this funding, they have developed methods known as Virtual Life Management® (VLM®), and obtained seven patents along the way. VEXTEC now provides services in the areas of production line reliability, risk assessment and durability prediction for manufacturing companies of structural, mechanical and electronic products. At the Southern Automotive Conference Dr. Tryon and Dr. Dey will be looking for manufacturers who could benefit from this technology. Both will be available after conference hours for detailed discussions.


Building Brand Loyalty While Delivering Better Products

recall graphicAccording to the National Highway Traffic Safety Administration, last year the auto industry recalled close to a third more vehicles in the U.S. (22 million) than it sold (just over 15 million). Recalls were up by a staggering 25 percent during 2013, which is the industry’s highest rate since 2004. It is no shock that these recalls can do immense harm to a manufacturer. In the automotive industry, an early response to an emerging issue can save a tremendous amount of money, and help preserve a business’s reputation.

Today’s manufacturing companies face a significant challenge as they work to balance the demands of the marketplace for better performing products against the need to bring new products to market faster, cheaper and with greater reliability all while improving the customers overall experience. In fact, in a recent article by Warranty Week, their data indicates warranty costs stabilized last year (for the first time in a decade) and questions if manufacturers are beginning to put more emphasis on the overall customer experience.

Since product failures stem directly from a combination of inferior product quality and how the product is used by the customer in the “real world,” manufacturers are faced with almost an impossible task. It is not feasible to physically test for the full range of customer experiences and usage scenarios. So, what is a manufacturer to do?

The answer is computational simulation. By improving modeling, simulation and utilizing computational testing of products before launch or at the first indication there may be a problem, manufacturers can help avoid expensive product recalls or get in front of a looming problem and deliver a better experience to their customer. That is where Virtual Life Management® (VLM) comes into play.  With VLM®, manufacturers can evaluate designs, material alternatives and the full statistical distribution of how the product could be used by the customer. VLM provides a more meaningful way of predicting customer experience and warranty expenses than traditional reliability projection methods alone while reducing physical testing requirements and cost.

An article published by WIRED Magazine discusses product recalls by US manufacturers and how computational simulation tools such as VEXTEC’s VLM helps companies overcome these challenges throughout a product’s life cycle. Over the past twelve years, VLM has simulated changes in design, material processing, and usage scenarios on over 100 successful projects for commercial and government clients. Using VLM, clients have resolved in-service reliability issues, and accelerated product development processes for a variety of fatigue and corrosion applications at substantially lower costs than traditional testing methods.

It is clear that today’s brands require a warranty solution that reduces costs and increases the customer’s lifetime value. VLM has the technology to deliver that solution.
