%0 Journal Article %T Comparison of isotropic elasto-plastic models for the plastic metric tensor $C_p=F_p^T\, F_p$ %A Patrizio Neff %A Ionel-Dumitrel Ghiba %J Mathematics %D 2014 %I arXiv %X We discuss in detail existing isotropic elasto-plastic models based on 6-dimensional flow rules for the positive definite plastic metric tensor $C_p=F_p^T\, F_p$ and highlight their properties and interconnections. We show that seemingly different models are equivalent in the isotropic case. %U http://arxiv.org/abs/1410.2818v2
