Abstract
The studies on crack‐tip plastic zones are of fundamental importance in describing the process of failure and in formulating various fracture criteria. The material fracture by opening mode (mode I) is not solely responsible for fracture propagation. Many industrial examples show the presence of mode II and mixed mode I+II loading in machine/structural components. In the present study, the emphasis is placed on the analysis of the size and shape of the plastic zone at the crack tip under mixed mode (I+II) loading conditions. The shape and size of crack‐tip plastic zones have been estimated by elastic finite element analysis in a Compact Tensile Shear (CTS) specimen under mixed mode loading according to von Mises yield criteria. The results obtained are used to analyze the minimum plastic zone radius (MPZR) criterion for crack‐initiation angle with reference to the loading angle and stress intensity factor.
