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, ...

A novel approach for the micromechanics analysis of composite structures is developed using refined beam models and the mechanics of structure genome (MSG). The MSG provides a tool to obtain the complete stiffness matrix of general composite materials by asymptotically minimizing the loss of information between the original heterogeneous body and the sought homogenized body. The constitutive in...

We investigate recovery of through-the-thickness transverse normal and shear strains and stresses in statically deformed functionally graded (FG) doubly-curved sandwich shell structures and shells of revolution using the generalized zigzag displacement field and the Carrera Unified Formulation (CUF). Three different through-the-thickness distributions of the volume fractions of constituents and...

The structural analysis of ultra-lightweight flexible shells and membranes may require the adoption complex nonlinear strain-displacement relations. These be approximated simplified in some circumstances, e.g., case moderately large displacements rotations, others not. In this paper, effectiveness various geometrically strain approximations such as von Krmn strains is investigated by making use...

In this paper we present a layerwise finite element model for the analysis of sandwich laminated plates with a viscoelastic core and laminated anisotropic face layers. The stiffness and mass matrices of the element are obtained by the Carrera’s Unified formulation (CUF). The dynamic problem is solved in the frequency domain with viscoelastic frequency-dependent material properties for the core....

This works proposes a novel approach to develop higher-order finite elements by taking progressive damage into account in the formulation.

Besides,...

Abstract. A new method for high-fidelity aeroelastic static analysis of composite laminated wings is proposed. The structural and the fluid-dynamic are coupled in a heterogeneous staggered process. Finite Element Method (FEM), Carrera Unified Formulation (CUF) Equivalent Plate Modelling (EPM) combined to model complex three-dimensional geometries bi-dimensional framework; Computational Fluid Dy...

Functionally graded materials (FGMs), proposed in 1980s by the Japanese school of material science as thermal barrier materials [1], present a number of advantages that make them attractive in potential future applications, such a reduction of in-plane and transverse through-the-thickness stresses, an improved residual stress distribution, enhanced thermal properties, higher fracture toughness,...

In this paper, the Carrera Unified Formulation and the generalized differential quadrature technique are combined for predicting the static deformations and the free vibration behavior of thin and thick isotropic as well as cross-ply laminated plates. Through numerical experiments, the capability and efficiency of this technique, based on the strong formulation of the problem equations, are dem...
