Topological sensitivity analysis of piezoelectric actuator

Résumé

The coupled model of a piezoelectric actuator is considered in the paper. For the specific shape optimization problem the shape-topological sensitivity analysis is performed. The obtained result can be used within the optimum design procedure of a micromechanism which transforms the electrical energy supplemented via its piezoceramic part into elastic energy of an actuator. The domain decomposition technique is applied in order to obtain the topological derivatives of the tracking-type functional defined on a part of the boundary of the elastic body under consideration. The proposed method is general and can be used for the purposes of the shape-topological sensitivity analysis for a broad class of multiphysics models.
