Abstract:
      Based on the foundational solutions of three dimensional piezoelectric materials,the basis idea of virtual boundary element method for elasticity and the linear superposition principle,this paper present a virtual boundary element-least square collocation method for three dimensional piezoelectric materials.Except the same merits as the conventional boundary element method,the most important advantage of this method is it can exclude the singular integral in conventional boundary element method.In the end,numerical solutions are compared with analytical ones to demonstrate the validity and high accuracy of the method.
