Abstract

A damage accumulation model for fatigue crack initiation was developed from the earlier theoretical work by Mura and coworkers. In this model, fatigue cracks are assumed to initiate when the strain energy density accumulated in a given slip band is equal to twice the surface free energy of the material. A simple scaling relationship analogous to the Coffin-Manson law can be derived for the fatigue life. This result is then compared with experimental data obtained from silver and copper single crystals.
