Dear Prof. Wolfgang,
Thank you for sharing the tutorial step.
I am using the plasticity (material non linearity) part of it with the
surface force (Neuman BC) as a mechanical load. When I remove the load the
plasticized domain comes back to its original (undeformed) state.
* I was wondering if this code with current mathematical model of
plasticity (as mentioned in the corresponding research article) could be
further developed to evaluate the plastic strain of the plasticized region?*
Moreover, this plastic deformation could be then stored on Gauss points so
that one can also visualize that what is the final shape of the plasticized
domain after removing load.
Thank you!
