Abstract. Equilibrium finite
elements models have been used, together with compatible formulations, for
error estimation and adaptive refinement in 2D and 3D elasticity problems. This
approach is based on the fact that, from these solutions, bounds of the error
of the outputs (global or local) can be obtained. Regarding the application of
these techniques to Reissner-Mindlin plates, we discuss in particular the
influence of the existence of a boundary layer in a soft simply supported plate.
