Slip line fields in a wedge compressed by a rough rigid flat die and the load or its upper and lower limits were obtained. The wedge has any inclination to the die face and the motion of die is arbitrary. The slip line fields are distinguished into three cases according to the direction of the motion. Although the upper and lower limits of the load were calculated by means of the extremum principle described in the first report, the application of this principle is not rigorous and must be justified from the numerical results. The partial solution where all conditions are satisfied in the assumed plastic region differs from the kinematically admissible field where the condition of equilibrium is not satisfied in view of the fact that the latter cannot determine the definite relation between the shape of the field and frictional coefficient at the contact face.
