Abstract

We present a theoretical approach for investigating the response of an active composite plate system containing elastic nonlinear actuation devices undergoing small strains. the model satisfies the equations of elasticity and Maxwell's governing equation by assuming that the flux through the thickness is a constant and that Kirchhoff-Love assumptions are applicable. This yields an electric field which varies linearly through the thickness and is consistent with the results of thin plate analysis for linear actuation materials. The analysis presented here is meant to provide an initial framework for modeling generic actuation systems behaving in a elastic nonlinear fashion. The model is presently coupled with a micro solution also incorporating a general set of constitutive relations. These two modeling efforts provide a means to optimize actuator geometry and architecture for specific applications. Preliminary results are presented for optimizing a simple linear active bimorph laminated plate system.
