Abstract

In this paper a methodology for prediction of fatigue crack initiation based on a representative scan of the material's microstructure is presented. The model utilizes local energy barriers against slip at the atomistic and continuum levels to construct an energy balance for the stability of a persistent slip band, which is a precursor to crack initiation. Scatter in the fatigue results is predicted based on various realizations of the material's measured microstructure and crystallographic texture.
