Abstract
The aim of this paper is to experimentally study the accuracy of the partial selective reduced integration (PSRI) scheme, for the numerical solution of the classical 2D Naghdi's shell model. In this work we consider a bending dom- inated shell as a benchmark problem and we analyze the convergence properties of the PSRI nite elements as well as their behaviour in presence of the locking phenomenon. Moreover we study the computed solutions in order to evaluate their dependence on dierent types of mesh, in particular if boundary layers appearFile in questo prodotto:
