RIGID-PLASTIC FINITE ELEMENT METHOD FOR FRICTIONAL MATERIALS

The rigid-plastic finite element method for frictional materials is developed and a stress-strain rate relation for rigid plastic materials of the drucker-prager type, under the assumption of the associated flow rule, is derived. 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, show a somewhat unreasonable velocity field due to the excessive effect of the dilatancy. Therefore, a numerical technique for the non-associated flow rule to reduce such an effect is developed. It is found that the dilatancy angle also influences the bearing capacity of the soil structure.
