Abstract

In this paper, a boundary element method (BEM) for the time-harmonic analysis of electromechanically (EM) coupled 3D structures is presented. Among the two components of an EM coupled structure, the piezoelectric transducer is modelled by a semi-analytical finite element method (FEM), and the host structure is formulated by the dual boundary element method (DBEM). The analysis of the coupled structure is performed in the Fourier domain. The electromechanical impedance (EMI) of the system is used for the purpose of detecting damages.
