Patent number: 8290753Abstract: The technology includes methods, a system, and a computer readable medium for predicting the time to failure of an electronic component, by generating a finite element model of the component, developing a microstructure-based failure model for each representative volume element associated with each node in the finite element model, and calculating a time to failure of the component from the shortest predicted time to failure of any node when a value of a stress variable is applied to the microstructure-based failure model of each node. The technology further includes methods, system, and a medium programmed to predict failure of a system that includes an electronic component, based on predicting time to failure of the component.Type: GrantFiled: March 13, 2007Date of Patent: October 16, 2012Assignee: Vextec CorporationInventors: Robert G. Tryon, III, Animesh Dey, Loren A. Nasser, Ganapathi Krishnan

Publication number: 20120078599Abstract: The invention provides a method and apparatus for predicting the failure of a component using a probabilistic model of a material's microstructural-based response to fatigue. The method predicts the component failure by a computer simulation of multiple incarnations of real material behavior, or virtual prototyping. The virtual prototyping simulates the effects of characteristics that include grain size, grain orientation, micro-applied stress and micro-yield strength that are difficult to simulate with real specimens. The invention provides an apparatus for predicting the response of a component to fatigue using the method.Type: ApplicationFiled: September 26, 2011Publication date: March 29, 2012Applicant: VEXTEC CORPORATIONInventor: Robert G.

Patent number: 8006544Abstract: An apparatus for testing failure of a material used in a jet engine, and more particularly to an apparatus that uses one or more model jet engine components made from a material used in a full-size jet engine and desired to be tested. The apparatus permits easy removal and disassembly of a jet engine mounted thereon as well as real-time measurements of run-time parameters. The methods and apparatus provide for predicting and analysing failure by a number of fatigue-related mechanisms including creep, fatigue, crack growth, foreign object damage, fretting, erosion, and stress corrosion.Type: GrantFiled: January 14, 2008Date of Patent: August 30, 2011Assignee: Vextec CorporationInventors: Richard Holmes, Robert G. Tryon, III, John E. Pope, Daniel A. Nasser, Michael Oja, Animesh Dey, Jesse Hamler, Jonathan Brooks, James Tryon
