VEXTEC to Present at the 2015 Aircraft Airworthiness & Sustainment Conference

VEXTEC's SCCrack SoftwareBrentwood, 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.

Tennessee’s Best Kept Secret

“Curiosity is lying in wait for every secret”-Ralph Waldo Emerson. 

Perhaps this was the goal of Tennessee Governor Bill Haslam in June when he returned from his economic development trip to Asia unwilling to share details with the public.  Soon after his departure, a flurry of news reports and blogs surfaced wanting to know why he would not share the details of his agenda with the public. His spokesman David Smith’s response was, “we don’t talk about private meetings.”  This left many to speculate if he was courting another automotive manufacturer to open up shop in the mid-state and what incentives and tax breaks were being offered to sweeten the deal.

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? Read more

Today’s Warranty Challenge: Building Brand Loyalty While Delivering Better Products

According 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. Read more
