A visco-hyperelastic approach to modelling rate-dependent large deformation of a dielectric acrylic elastomer
Source abstract
Abstract
In this work, a new visco-hyperelastic constitutive model is proposed to describe the rate-dependent large deformation behaviour of an acrylic elastomer. The proposed model is based on the Zener model, which consists of a hyperelastic equilibrium spring and a Maxwell element to capture rate-dependent material response. The constitutive equation is based on the history integral of Gent strain energy function. The material constants of the developed model are determined with the aid of available different rate-dependent uniaxial tensile experimental results. The proposed model is validated with the earlier published experimental results of VHB 4910 acrylic elastomer which is considered now as one of the promising actuator materials. Fittings of the proposed model with the earlier published experimental results and present experimental stress-stretch results in different strain rates are found to be in good agreement.
