A minimum principle for the law of dry friction was established in Part 1 of this paper. Here, in Part 2, the principle is applied to the nonsteady contact problem in which the traction evolves under the influence of a gross motion and loading program, and the principle appears to lead to a time sequence of linear programming problems. Such contact problems under several restrictions have been treated before by Kalker [3–5] without the aid of minimization techniques. In the present paper these restrictions are all removed. Numerical results are presented.
