摘要
A mechanical model is proposed to describe fatigue crack growth rate when the crack is subjected to mixed mode (I+II) loading. In the crack tip stress-strain distribution the modified Hutchinson solution is adopted. The model is based on maximum plastic strain energy density release rates at the tip of the crack. The required data for predicting fatigue crack growth rate can be found in standard material handbooks where cyclic and fatigue properties of the materials are presented.
