Two-yield elastoplasticity solver

Time-dependent 2D elastoplasticity solver for a two-yied model.

2D elastoplasticity solver for a time dependent two-yied model, which generalizes a classical model of linear kinematic hardening and features a hysteresis behaviour.

This is an updated version of Jan Valdman's code from his PhD thesis on Mathematical and Numerical Analysis of Elastoplastic Material with Multi-Surface Stress-Strain Relation submited at 2001 at the Christian-Albrechts-University of Kiel, Germany.

To run the code, type "start"

to generate a hysteresis curve describing the behaviour of the elastoplastic continuum under periodical time-dependent traction forces.
