The approximation is considered of some stationary elastic-perfectly problems formalized by G. Duvant and J. L. Lions. The main purpose is to derive error estimates for the approximation of the stress field sigma given by a finite element method, considered by B. Mercier. The approximate problems solved will be in terms of the displacements, which are the natural variables for computation.
