Abstract
This paper summarizes a nonlinear technique for quantifying the displacements generated in THUNDER actuators in response to applied voltages for a variety of boundary conditions and exogenous loads. A PDE model is constructed using Newtonian principles to quantify the displacements in the actuator due to field inputs to the piezoceramic patch. A free energy based hysteretic stress-strain relation is employed to model the electromechanical coupling in the PZT. A finite element method and Crank-Nicholson scheme are developed to discretize the model; properties of the model are illustrated through comparison with experimental data.
