摘要：
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 1) is not lonely 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, an emphasis is laid to study the size and shape of the plastic zone at the crack tip under mode I, mode II and mixed mode I + II loading conditions. The shape and size of crack-tip plastic zones have been estimated in a Compact tensile shear (CTS) specimen under mixed mode loading according to von Mises yield criteria. The results obtained are analyzed with reference to loading angle and effective stress intensity factor.
