Formulation and computation of geometrically nonlinear anisotropic inelasticity

摘要

The main objective of this contribution is the development of a thermodynamically consistent and modular formulation of anisotropic multiplicative elasto-plasticity. Based on the framework of standard dissipative materials, we introduce as a key-ingredient additional symmetric arguments - typically structural tensors - into the relevant scalar-valued isotropic tensor functions. Then the fundamental covariance relation allows a set up directly in terms of spatial fields and a convenient implementation within any numerical setting.
