Abstract

An assessment of multilayered finite plate elements in view of the fulfillment of the C^-Requirements E. Carrera & L. Demasi Dipartimento di Ingegneria Aeronautica e Spaziale, Politecnico di Torino, Italy Abstract This paper assesses finite element theories of multilayered plates subjected to static loadings in view of the fulfillment of so-called C®-requirements. Classical models formulated on the basis of Principle of Virtual Displace- ments, PVD, are compared to corresponding models based on Reissner Mixed Variational Theorem, RMVT. The latter one permits to assume two independent fields for diplacement and trasnverse stress components lead- ing to complete and a priori fulfillment of C®-requirements. Both layer- wise and equivalent-single-layer cases have been implemented. Linear up to fourth-order displacement and transverse stress fields are considered. Nu- merical assessment is given for a cross-ply plates under transverse pressure. It is concluded that finite elements formulat
