Variational Approach in Optimal Design of Piezoelectric Sensors & Actuators

Abstract:

A new optimization problem for laminated multilayered structures having surface bounded piezoelectric patches have been formulated and solved. The present formulation introduces boundaries of piezoelectric patches as new class of design variables. In addition classical design variables in the form of ply orientation angles of orthotropic layers are also taken into account. The design objective is the minimization of normal maximal deflections. The standard Rayleigh-Ritz method is used, however, the accuracy of optimal design are verified with the aid of the FE package ABAQUS. Examples are presented to illustrate the performance of the proposed model.
