Abstract

An integrated transgranular and intergranular crack growth method (ITICGM) is proposed to simulate short crack growth under corrosion fatigue. In this method, the microstructure-sensitive fatigue model and crystal plasticity-based fatigue indicator parameter (FIP) are used to describe microstructural fatigue damage in representative volume elements consisting of multiple grains. Corrosion effect is also taken into account to accurately predict the behavior of intergranular crack segments by introducing a hydrogen-diffusion informed cohesive zone model. With the proposed corrosion-informed methodology, the scattering crack behavior of steel under high cycle fatigue (HCF) is numerically observed and comparatively studied with three approaches such as transgranular crack growth method (TCGM), ITICGM, and corrosion-informed ITICGM.
