Paper Abstract

This paper deals with the rate and time dependent electrical and mechanical properties of Biaxially stretched Form I PVDF and modeling those properties. Experiments have been done to characterize the rate and time dependent mechanical behavior of PVDF and the rate dependent electrical properties of PVDF. The rate dependent mechanical property of PVDF has been modeled through a Kelvin solid with fractional dashpot and nonlinear spring assuming incompressibility. It is shown in this paper using the model, that the viscoelastic behavior of PVDF is similar to that of a Non-Newtonian fluid. The model predicts the response of PVDF properly within the range or 12% strain. The time dependent behavior of PVDF is modeled through a power law model.
