Two-active-plane finite element model in Mohr-Coulomb elastoplasticity. (English) Zbl 0952.74077

Summary: This paper presents an exact finite element formulation based on two-active-surface Mohr-Coulomb model. The formulae can be easily used in existing finite element codes. Numerical studies show that the two-active-surface model has some advantages over the traditional one-active-surface model.
