摘要

A modification of the thermodynamic microplane elasto-damage model accounting for the particular properties of particle based recycling materials is presented. The material model considers the transversely isotropic elastic as well as the anisotropic damage behavior of such material types. The initially isotropic microplane model is extended to a transversely isotropic model by modifying the free energy function on the microplane level by means of anisotropy functions depending on the distinguished material direction and the orientation of the microplanes. The modified microplane model is studied on the material point level and applied to a three-dimensional finite element analysis of a simple tension test.
