Exact solutions for Mohr Coulomb elastoplasticity are developed. Using these solutions an exact stress increment for a given finite strain increment can be computed. The developed solutions are valid for perfect and linear hardening/softening plasticity using isotropic work hardening hypotheses. The solutions can be used to check computer codes and assess their ability to handle multiple active yield surfaces. Illustrative examples are included.
