Description
Summary:In this study, results from monotonic uniaxial and biaxial stretch experiments carried out on rectangular uniaxially stretched PVDF thin samples, is reported. Both mechanical and electromechanical response of the film is reported in the study. Non-linearity in mechanical and electromechanical response is observed. Anisotropy in mechanical and electromechanical response is also noted from uniaxial and biaxial experiments. Constitutive models that are developed to capture (a) nonlinearity and (b) anisotropy are reported both for a mechanical and electromechanical response.
