Kurzfassung englisch:
A straightforward extension of the return mapping algorithm for J_2-plasticity at finite strains to a nonassociative Drucker-Prager yield criterion, assuming elastic volumetric response, is presented. It is shown that the concept of plastic incompressibility, assumed at the outset, does not hold for a certain range of stresses.
