Linear response of thin axysimmetric cross-ply structure under a static load: Numerical and analythical comparisons

Abstract. Thin-walled mechanical components, such as beams, plates and shells, are widely used structural components in several engineering fields, particular mechanical, aeronautical aerospace sectors. The purpose of this work is to analyse the cross-ply bending behaviour cylindrical spherical shell structures using finite element method. Hence, numerical models, realized commercial software, were solid approaches compared with analytical methods appreciate their advantages. In research, a Navier solution close form for high-order theories, developed Carrera Unified Formulation (CUF) approach, has been reported, where elastic model variational principle virtual three-dimensional linear theory equations results obtained Mathematica software. furnished by method elasticity solutions given literature Navier’s benchmark comparing terms maximum displacement stress distribution along principal structure direction. However, cannot provide sufficient data describe tensional deformational state at all points especially laminate thickness. Wishing obtain complete description plate's behaviour, it necessary use approach associated increase calculation time. contrast, based on CUF shows very efficient composite its should be preferred classical lamination if an accurate necessary.
