The aim is to develop a phenomenological material model for describing the elastic-plastic behavior of anisotropic materials. The focus is on materials in which the anisotropic structure deforms together with the material, for example fiber-reinforced materials. This behavior has been coined "Material Plasticity" by Forest and Parisot (2000).For the development of this theory the anisotropic flow and thus the determination of the evolution equations are of central importance. The required material parameters are determined by using the finite element method with a representative volume element (RVE). Afterwards, the theory should be experimentally validated. As a starting point for the further development of this theory serve the already published comments on material plasticity in Bertram (2012).
