Abstract: Wide research is being carried on to investigate effect of electromechanical coupling behavior on fracture and crack growth of piezoelectric materials. In the present paper quasi-static crack growth using semi-permeable crack boundary conditions in a piezoelectric material has been analyzed using the extended finite element method (XFEM). Combined Mechanical and Electrical loading has been applied on a pre-cracked rectangular plate made of piezoelectric material with crack at its edge and centre. Stress intensity factors have been evaluated by interaction integral approach using the asymptotic crack tip fields.
