Overview

Fatigue is the weakening or failure of a material caused by repeated applied loads. It combines the material’s multiscale internal structures with the cyclic boundary conditions (loads, displacements, etc.) generating ultimate failure. The maximum stress that causes such failure may be much less than the yield or ultimate strength, because of the internal damage progression due to local heterogeneities inducing stress concentrations.

MultiStage Fatigue Model

The microstructure-based multistage fatigue (MSF) model of McDowell et al. (McDowell et al., 2003) is an appealing model for prognosis applications, particularly in the HCF regime, since it captures fatigue behavior in the initial stages of crack incubation (formation and growth within the zone of influence of inclusion or defect where formed) and small crack growth, and explicitly addresses the role of microstructure.
