Remarks on some mixed finite element schemes for Reissner-Mindlin plate model

Two different stabilization procedures for mixed finite element schemes for Reissner-Mindlin plate problems are introduced. They are based on a suitable modification of the discrete shear energy like that introduced when a partial selective reduced integration technique is used. Some numerical results will be presented in order to show the performance of these schemes with respect to the locking phenomenon. The dependence of the approximate solution on the stabilizing parameter is also analyzed.
