Fracture analysis of edge cracked FGM plate under compressive load along crack

Abstract

Fracture analysis of FGM plate with edge crack under compressive point load along crack is carried out by using extended finite element method (XFEM). In this present work a FGM plate where material properties vary along width with edge crack is considered for the study. The mathematical formulation is carried out in MATLAB and the stress distribution and mixed mode stress intensity factors (SIFs) are obtained for different position of point load. The validation study is carried out for developed MATLAB code with previously published research paper and then fracture analysis of FGM plate with crack under compressive point load along crack is investigated. The present study is carried out to understand the fracture resistance of edge crack FGM plate when the action of load is along crack.
