Original Abstract

Soft tissues are pseudoelastic materials, modelled mostly as hyperelastic. In this theory, the non-linear relations between stress and strain components are described by various strain energy density functions, preferably by anisotropic ones. For any hyperelastic materials, isotropic as well as anisotropic, uniaxial extension tests are not sufficient for a reliable determination of parameters of multi-dimensional constitutive models that aim to predict the material behaviour in different types stress-strain states. Therefore it is necessary to use some appropriate additional types of tests for experimental identification of constitutive parameters. Based on experimental data from various types of biaxial tension tests, this paper presents a determination of parameters of anisotropic hyperelastic models.
