In an earlier study [16] the nonlinear behaviour of unimodular laminated plates was studied. This paper, following the previous study, concerns a large deflection analysis of moderately thick rectangular plates having arbitrary boundary conditions and finite thickness shear moduli. The plates are manufactured in bimodular materials and constructed in a cross-ply fashion or in a single layer with arbitrary fibre direction angle. Numerical results are obtained by a finite element technique in which are specified five degrees of freedom, three displacements and two bending slopes per node. Furthermore, the effects of plate aspect ratio, bimodularity ratio and fibre orientation are studied; finally, comparisons with some results available in literature are also given.
In una precedente Nota [16] è stato studiato il comportamento nonlineare di piastre laminate composite realizzate in materiale unimodulare. In questo lavoro, proseguendo lo studio precedente, viene analizzato il comportamento non lineare di piastre rettangolari moderatamente spesse arbitrariamente vincolate. Le piastre sono realizzate in materiale bimodulare e modellate secondo lo schema cross-ply ovvero in una singola lamina avente una arbitraria orientazione della direzione delle fibre. I risultati sono ottenuti adottando una tecnica computazionale agli elementi finiti considerando, per ogni nodo, cinque gradi di libertà: tre componenti di spostamento e due rotazioni flessionali. Inoltre vengono studiati gli effetti del rapporto di forma, del rapporto di bimodularità e della direzione delle fibre; vengono, infine, riportati alcuni confronti con risultati reperibili in letteratura.
