Analytical and numerical tools for the analysis and design of actuated polymer films (APFs) are developed and described in this paper. Computational micromechanical models are set up and correlated in order to calculate the deformation and power requirement to actuate an APF taking into account hyperelastic and viscous effects. A method is developed to correlate material parameters in the viscous branch of the Bergstrom-Boyce model to available experimental data. The effects of various geometric and material parameters are elucidated by a parametric study including coherent versus non-coherent actuators, excitation frequency and magnitude, modulus of elasticity of the actuator and the top film, and actuator volume fraction.
