A shear deformation theory is developed to analyse the geometrically nonlinear behaviour of layered composite plates under transverse loads. The theory accounts for the transverse shear (as in the Reissner Mindlin plate theory) and large rotations (in the sense of the von Karman theory) suitable for simulating the behaviour of moderately thick plates. Square and rectangular plates are considered: the numerical results are obtained by a finite element computational procedure and are given for various boundary and loading conditions, a/b ratios, stacking and orientation of layers and material properties (E1/E2 ratio, E1/G ratio, etc.).

In questo lavoro si sviluppa una teoria che tiene conto della deformabilità tagliante allo scopo di analizzare il comportamento di piastre laminate composite sottoposte a carichi flettenti. La teoria tiene conto delle deformazioni dovute al taglio (nel senso della teoria delle piastre spesse di Reissner-Mindlin) e di rotazioni moderatamente grandi (nel senso della teoria di von Karman). I risultati numerici, relativi a piastre rettangolari, sono stati ottenuti attraverso una procedura computazionale agli elementi finiti considerando varie condizioni di vincolo e di carico, diversi valori del rapporto a/b, differenti spessori ed orientazioni delle lamine e proprietà dei materiali (rapporto E1/E2, rapporto E1/G, etc.).
