压电体表面Maxwell应力对断裂的效应
Effects of Surface Maxwell Stress on Fracture of Piezoelectric Solids
摘要
Abstract
Effects of surface Maxwell stresses on the fracture of a piezoelectric solid with a crack is studied. Based on complex function method combined with Stroh formalism, the influences of dielectrics in the surrounding space and inside the crack on the electric fields, crack opening and field intensity factors are investigated, respectively. And then numerical examples are presented under pure electric loading and combined mechanical-electric loading to discuss the fracture behaviors of the solid. It is shown that the surface Maxwell stresses play an important role in the fracture of the piezoelectric solid.关键词
