Extended finite element simulation of stationary dynamic cracks in piezoelectric solids under impact loading

This work presents a transient dynamic analysis of stationary cracks in two-dimensional, homogeneous and linear piezoelectric solids subjected to coupled electromechanical impact loads using the extended finite element method (X-FEM). To serve this purpose, a dynamic X-FEM computer code using quadrilateral elements in conjunction with the level set method to accurately describe the crack geometry is developed. The sixfold basis enrichment...
