Abstract By means of Non-Uniform Rational B-Splines (NURBS) curves, it is possible to
describe arbitrary shapes with holes and discontinuities. These peculiar shapes can be …

A numerical procedure based on the Generalized Differential Quadrature (GDQ) method is
presented to solve the strong form of the differential equations that govern the free vibration …

The stiffness-tailoring capability of Variable Angle Tow (VAT) laminates gives enhanced
freedom to design thin-walled structures. One key advantage of tow steering is the ability to …

In this paper we show how to significantly improve the robustness and the efficiency of the
Newton method in geometrically non-linear structural problems discretized via displacement …

Local buckling and post-buckling of thin-walled composite channel-section beams under
pure bending are described. Profiles were subject to bending in the plane of the lowest …

A corotational flat shell element for the geometrically nonlinear analysis of laminated
composite structures is presented. The element is obtained from the Hellinger–Reissner …

The Koiter method recovers the equilibrium path of an elastic structure using a reduced
model, obtained by means of a quadratic asymptotic expansion of the finite element model …

Numerical formulations of the Koiter theory allow the efficient prediction, through a reduced
model, of the behavior of shell structures when failure is dominated by buckling. In this work …

The design of lightweight structures is often driven by buckling phenomena. Increasing
demands for fuel-efficient aircraft structures makes post-buckled designs attractive from a …

In this paper we propose a powerful tool for the evaluation of the initial post-buckling
behavior of multi-layered composite shells and beams in both bifurcation and limit load …
