The problem to find the optimal thickness of a plate in a set of bounded Lipschitz continuous functions is considered. Mean values of the intensity of shear stresses must not exceed a given value. Using a penalty method and finite element spaces with interpolation to overcome the ``locking'' effect, an approximate optimization problem is proposed. Its solvability is proved and some convergence analysis is presented.
