Abstract

We obtain a simple model for the eletromechanical motion of a linear piezoelectric rod with quasi-static domain switching. We start from the 3D linear piezoelasticity and by using suitable mechanical internal constraints and electrical semi-inverse hypotheses, we arrive at a 1D enthalpy functional. By using standard variational techniques then we get 1D equations of motion for extension and bending which show the coupling between the mechanical and electrical properties of the material.
