Numerical study of edge crack interaction with inclusion and void of an isotropic plate under different loadings by extended finite element method

Abstract

In the present work Extended Finite Element Method (XFEM) is utilized for interaction study of cracked isotropic plate under different loading conditions. XFEM is a powerful tool to handle fracture mechanics problems where, extra enrichment functions for the crack faces and tip are get utilized. In this present work main focus is interaction study of edge cracked isotropic plate with inclusion and void under tensile, shear, combined (tensile and shear) and exponential loading. Here, MATLAB environment is used to evaluate mixed mode stress intensity factor (MMSIF) of edge cracked isotropic plate when interacted with inclusion and void.
