Abstract
A mechanical model for a piezoelectric plate actuator is developed. The effects of the piezo-actuation as well as the equivalent effect of thermal pre-stress are included in the constitutive model. Based on classical lamination theory we derive a formulation for the plate behavior including piezoelectric effects and thermal strains. Using von Karman plate theory we obtain equilibrium equations able to describe the non-linear behavior of the plate. The equilibrium equations are numerically solved for axisymmetric
plates using the shooting method to obtain equilibrium paths.
