Two-yield elastoplasticity solver
Provided Matlab software demonstrates two-yield elastoplasticity quasi-static calculation. Theory and numerics can be found in Jan Valdman's PhD thesis:
Mathematical and Numerical Analysis of Elastoplastic Material with Multi-Surface Stress-Strain Relation
submited at Christian-Albrechts-University of Kiel, and published at Dissertation.de Verlag in Berlin in 2002 under ISBN 3-89825-501-8.
A pdf version of the thesis can be downloaded here.
I will be happy to get any comments/suggestion on Jan.Valdman@sfb013.uni-linz.ac.at.
Two animations from the Matlab solver (colors meaning: black - elastic zone, brown - first plastic zone, light yellow - second plastic zone):
