A refined assumed strain finite element model for statics and dynamics of laminated plates

This work discusses some alternate models of a mixed assumed strain finite element which has been developed for laminated plates. After a brief theoretical review about this kind of plates and their possible finite element formulation, specifically devised for predicting the mechanical behavior of such structures, we discuss four possible assumptions for strains generating four kinds of mixed assumed strain finite elements. Several numerical tests performed on the aforementioned finite elements are thoroughly discussed in order to sketch some guidelines which can be useful when dealing with laminated plate problems.
