PSRI schemes for shells: a benchmark study
The aim of this paper is to study experimentally the accuracy of the partial selective reduced integration (PSRI) scheme, for the numerical solution of the classical 2D Naghdi shell model. In this work we consider a bending dominated shell as a benchmark problem and we analyze the convergence properties of the PSRI finite elements as well as their behavior in the presence of the locking phenomenon. Moreover we study the computed solutions in order to evaluate their dependence on different types of mesh, in particular if boundary layers appear.
