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
