Abstract : We analyze the robustness of various standard finite element schemes for the Reissner-Mindlin plate and obtain asymptotic convergence estimates that are uniform in terms of the thickness d. We identify h version schemes that show locking, i.e. for which the asymptotic convergence rate deteriorates as d (right arrow) 0 and also show that the p version is free of locking. In order to isolate locking effects from boundary layer effects (which also arise as d (right arrow) 0, our analysis is carried out for the periodic case, which is free of boundary layers.
