Paper Abstract

A transient analysis, using the finite element method, is presented to study the behavior of piezoelectric materials, including non-linear plasticity effects. The analysis involves the development of an elastic-plastic constitutive law for piezoelasticity. A mixed implicit-explicit integration scheme is constructed to solve the finite element equations so as to exploit the highlights of both transient integration methods. The developed program is used to study the transient behavior of a piezoelectric actuator. Linear solutions show an edge effect resulting in changes in the curvature of the surface during the initial step transient response. The effects of plastic deformation on the behavior of a piezoelectric actuator are presented. Such calculations can be used to predict behavior of a sensor or actuator after an extreme loading event.
