In this paper, for the first time, the boundary element method (BEM) is used for modellingsmart structures instrumented with piezoelectric actuators and sensors. The host structure andits cracks are formulated with the 3D dual boundary element method (DBEM), and themodelling of the piezoelectric transducers implements a 3D semi-analytical finite elementapproach. The elastodynamic analysis of the structure is performed in the Laplace domain andthe time history is obtained by inverse Laplace transform. The sensor signals obtained fromBEM simulations show excellent agreement with those from finite element modellingsimulations and experiments. This work provides an alternative methodology for modellingsmart structures in structural health monitoring applications.
