It is considered a quasistatic elastoplastic model contaning the Drucker-Prager yield criterion, a nonassociative plastic flow rule and a nonlinear isotropic hardening. The problem is discretized by the implicit Euler method in time. For discretization in space, two type of finite elements can be used: linear simplicial elements or 8-point quadrilateral elements with 9-point numerical quadrature. The code contains an improved return-mapping scheme developped for nonsmooth plastic potentials. Further, the semismooth Newton method is used for solving nonlinear systems of equations.
