BEM for Static and Dynamic Fracture Analysis in Thin Piezoelectric Structures

Abstract:

A 2D time-domain boundary element method (BEM) is developed to study the fracture problems in thin piezoelectric structure. The nearly singular integrals arisen in thin structures are calculated in two ways. One is based on a nonlinear coordinate transformation for curve-quadratic element, and the other one is an analytical integration method for straight quadratic element. Numerical examples are presented to verify the effectiveness and stability of the present BEM in thin piezoelectric structure.
