摘要
The paper concerns the development of a time dependent constitutive model of polyvinylidene fluoride (PVDF), a thin film piezoelectric polymer. Experimental evidence indicates that PVDF thin films can be characterized as orthotropic materials with different material properties in regard to the orientation of the aligned molecular chains of the polymer. Based on the experimental results, the constitutive equations of linear hereditary viscoelasticity are used to characterize the mechanical properties of PVDF.
