Consistent polynomial expansions of stored energy function for incompressible hyperelastic materials

Abstract

In the article, hyperelastic material models which state consistent polynomial expansions of the stored energy function are discussed. The approach follows from the muliplicative decomposition of the deformation gradient. Some advantages of the third order expansion model over the five-parameter Rivlin model using Treloar's experimental data are shown. The models are qualitatively and quantitatively compared to highlight these advantages of the discussed MV model.
