The Physics of Fatigue- Part 1 – Nucleation

This is the first installment of a new blog series on the physics of fatigue.  It has been adapted from the upcoming Ph.D. dissertation of VEXTEC’s Robert McDaniels.

Fatigue can best be considered as a process, rather than an event [1, 2].  The fatigue process begins as soon as a component is manufactured and enters service, and proceeds through the life of the component in stages. From the perspective of modeling and simulation, there are 4 stages of the fatigue life of a component: Read more


VEXTEC Presenting at AVTech 2017

avtech_2017VEXTEC is excited to be apart of this year’s Air Vehicles Technology Symposium (AVTech 2017).  Dr. Bob Tryon, CTO of VEXTEC, will be presenting Finite Element Modeling Correlation during the Airframe Digital Twin/Digital Thread session on Thursday, October, 26th at 2:00 p.m.   This Symposium will bring together engineers, scientists, leaders, and operational personnel from throughout the air vehicle community, including the Army, Navy, Air Force, NASA, DARPA, FAA, OSD, air vehicle integrators, component and material suppliers, and academia.
