A thin plate made of a plastic material obeying the Hencky-Mises stress-strain law is considered. On a part of the boundary displacements and/or rotations with friction are prescribed. The model leads to a variational inequality of the second kind with a monotone operator. Since the material function, loading and the friction coefficients are uncertain, the method of the worst scenario is employd. Convergence of approximate solutions is proved.
