Computational Simulation of 3D Fatigue Crack Growth under Mixed-Mode Loading

The purpose of this research was to present a simulation modelling crack propagation trajectory in linear elastic material subjected mixed-mode loadings and investigate the effects existence hole geometrical thickness on fatigue growth life under constant amplitude loading. For various geometry thickness, (I/II) studies were carried out utilize single edge cracked plate with three holes compact tension shear specimens loading angles. Smart Crack Growth Technology, new feature ANSYS, used ANSYS Mechanical APDL 19.2 predict cracks’ their consequent associated evaluating stress intensity factors. maximum circumferential criterion is implemented as direction fracture mechanics (LEFM). According position, results demonstrate that grows towards due unbalanced stresses induced tip. are verified terms paths, factors, load conditions, several published literature showing consistent results.
