Paper Abstract

Boundary element methods are attractive tools in the analysis of complex coupled problems. This method has been used in several engineering disciplines as a computationally efficient and versatile technique. Three boundary element methods that can be used to analyze linear electroelastic response of piezoelectric materials are presented in this paper. The three methods described in this paper are identified as the direct boundary element method, fictitious stress-electric charge method and the indirect boundary element method. The formulation of the three methods is discussed. Closed form solutions for the kernel functions appearing in the integral equations are also presented for the 2D case. The methods can be extended to 3D problems involving piecewise nonhomogeneous piezoelectric materials.
