A micromorphic continuum formulation for cardiac tissue mechanics
Abstract eng: The material composition of cardiac tissue is highly heterogeneous and non-uniform in terms of its elastic and anisotropic properties. In contrast to classical models, generalized continuumbased formulations can account for higher-order effects arising from heterogeneous material behaviour by linking them to extra degrees of freedom and corresponding additional strain and stress quantities. Here, we want to adopt a generalized continuum framework described in Sansour et al. (2010) which is based on the mathematical description of a combined macro- and micro-space. The approach introduces additional degrees of freedom which constitute a so-called micromorphic deformation. The ability to implicitly account for scale-dependent higher-order deformation effects in the constitutive law gives this approach an advanced material description over classical formulations.
