Abstract
We consider the approximation of the Reissner–Mindlin plate model by the standard Galerkin p version finite element method. Under the assumption of sufficient smoothness on the solution, we illustrate that the method is asymptotically free of locking even when certain curvilinear elements are used. The amount of preasymptotic locking is also identified and is shown to depend on the element mappings. We identify which mappings will result in asymptotically locking free methods and through numerical computations we verify the results for various mappings used in practice.
