This lecture discusses the upper bound of the superficial foundation problem for a Tresca material, using a kinematic approach to determine the bearing capacity. It covers the derivation process, the choice of a failure mechanism, the application of virtual powers principle, and the calculation of resistance power. The lecture also explores the geometric parameters, the calculation of external effects power, and the dissipated power in the volume. It concludes by applying the obtained solution to non-drained loading conditions in practical scenarios.
