Modeling of biaxial response of Polyvinyledene Fluoride (PVDF)

Abstract eng:
Polyvinylidene Fluoride (PVDF) is a piezo polymer and exhibits both sensor and actuator effects for different potential applications in industries. In this study the experimental and modelling results of monotonic biaxial response of PVDF will be presented. A non contact speckle monitoring method was used to monitor point wise finite deformation in the specimen. A hyper elastic constitutive model using four invariants was used to capture the anisotropy in the mechanical response. A paper reports a good correlation between the proposed model and the observed experimental data.
