Abstract
The generalized plasticity model as presented by Lubliner (1991) and applied by Taylor and Auricchio (1995) is an extension of classical rate independent plasticity with a yield surface. For the generalized plasticity concept in Huettel and Matzenmiller (1999a) an integration algorithm under the restrictions of plane stress is presented that reduces the discretized tensor equations in the case of isotropy even for nonlinear hardening to the solution of a single scalar equation, as it is typical for the classical J(2)-plasticity model in the complete three-dimensional case.
