Problem 1. rectangular plate ofelastic-plastic material with Mises criterion subjected
to ramp loadings. Progress ofthe plastic zone is shown. Deflections are compared with
the solutions obtained by using ANSYS.
Problem 2. A rectangular plate ofelastic-plastic material with Drucker-Prager criterion
subjected to ramp loadings.
