| Abstract: | A framework for material models describing finite plastic deformations is established by the assumption of isomorphic elastic ranges. The concepts of decomposition into elastic and plastic deformations is not needed, neither intermediate configurations. A comparison with other approaches is given and shows their range of validity. |
