• The rigid-plastic finite element method for frictional materials is developed. We derive the stress-strain rate relation for rigid plastic materials of the Drucker-Prager type under the assumption of the associated flow rule. We show that it is convenient in the derivation to decompose the stress into two components which are similar to the mean and deviatoric ones in case of materials of the von Mises type.The materials with a relatively high internal friction angle, however, shows somewhat unreasonable velocity field due to the excessive effect of the dilatancy. Therefore, we also develop a numerical technique for the non-associated flow rule to reduce such an effect. We find that the dilatancy angle influences the bearing capacity of the soil structure as well.
