This code demonstrates a time-dependent evolution of the continuum undergoing combined elasto-plasto-damage transformation. Details of considered material models, its numerical analysis and computations are explained in two papers:

2. T. Roubíček and J. Valdman: Stress-driven solution to rate-independent elasto-plasticity with damage at small strains and its computer implementation. Mathematics and Mechanics of Solids 22, No. 6, 1267-1287 (2017)

Call 'start' in the 'solver_elasto_plasto_damage' directory to run the code.
There are two different model cases, that can be run by setting the value of the variable 'test' in the 'start.m' file:
'test=1' - order of transition: elasticity -> damage -> perfect plasticity, it corresponds to paper 1.
'test=2' - order of transition: elasticity -> plasticity with hardening -> damage, it corresponds to paper 2.
