Abstract

In this work, the finite element method is used together with Hamilton's principle and generalized heat equation for the modeling of thermopiezoelectric media. The robustness of a thermopiezoelectric actuator pair bonded to a cantilever beam structure is then studied using the derived finite element equations in Taguchi methodology. Three case studies are considered in order to investigate the parameters affecting the control performance and the influence levels of these parameters.
