Abstract

In this paper, the numerical solution of piezoelectric problems by means of two discretization methods — the Finite Element Method (FEM) and the Boundary Element Method (BEM) — is described. At first, using the equations of elastostatics, the similarities and differences of the methods are explained and some of their advantages and disadvantages are pointed out. After this, the piezoelectric formulations of both methods are introduced. A numerical example serves to demonstrate the excellent agreement of the FEM and BEM results as well as to show the superiority of the BEM in the calculation of elastic stresses and the electric field.
