A Numerical Estimation of Fatigue Crack Tip Plastic Zone Size and Shape under Mixed-Mode Loading Condition

Article Preview

Abstract:

A 2D elastic-plastic FEM simulation of growing fatigue crack under combined mode I and II loading was performed. An inclined fatigue crack propagated in a sheet of an Al-alloy D16CT1. The effect of increasing mode-mixity on cyclic zone size, shape and the amount of dissipated energy was investigated.
