VEXTEC to Present at the 2014 Aircraft Airworthiness & Sustainment Conference

NASHVILLE, Tenn. - April 11, 2014 - PRLog -- VEXTEC to Present at the 2014 Aircraft Airworthiness & Sustainment Conference

VEXTEC Corporation will be making three presentations at the 2014 Aircraft Airworthiness & Sustainment (AA&S) Conference.  The conference will be held in Baltimore, Maryland April 14-17.  Representatives from the Air Force, Navy, NASA, Federal Aviation Administration and industry will be in attendance. Over 90 papers will be presented. VEXTEC co-founders Robert G. Tryon and Animesh Dey will be making presentations.

Robert Tryon will be presenting “Multi-Scale Modeling of Corrosion-Fatigue in AA 7XXX Alloys at the Material Microstructural Level.”  Traditional industry solutions for corrosion-fatigue prediction have relied on empirical damage models. These models cannot be generalized to study conditions beyond those represented in the test database used to develop the model. VEXTEC’s method is a completely new approach by creating a generalized computational framework corrosion-fatigue software tool using Monte Carlo simulation with systems engineering and microstructural analysis. The model predicts fatigue degradation due to corrosion for real materials and real structures for any alloy, in multiple corrosive environments.

The second VEXTEC paper will be presented by Animesh Dey and is entitled “Uncertainty Propagation In Multi-Disciplinary Computational Analysis.” Simulation-based design and certification is fundamentally about making decisions with uncertainty. However, minimizing uncertainty comes at a price – more testing to better define the variability in input parameters and higher fidelity analyses at a finer scale to limit the uncertainty in the physics, etc. VEXTEC is developing these methods for the US Air Force under the Airframe Digital Twin program. The methodology will evaluate the propagation of error and uncertainty from three key disciplines - aerodynamic, structural and fatigue.

Animesh Dey will present “Probabilistic Virtual Inspection for Condition Based Maintenance.”  The US military is in the process of shifting its current weapon system focus from procurement to sustainment.  VEXTEC was contracted by the Air Force Office of Scientific Research to develop a prototype fleet management tool. The goal of the development effort was to create a fleet management/availability decision tool, taking into account the very real variations in operational service time between inspections and operational mission severity.

VEXTEC (http://www.vextec.com) was founded in 2000 and has developed its patented technology primarily through Department of Defense Small Business Innovative Research programs. VEXTEC offers its Virtual Life Management software  and services to a variety of commercial and government customers.
