A reliability-based optimization framework is introduced and used to design filament-wound
cylindrical shells with variable angle tow. Seven design cases are investigated to enable a …

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 …

The optimal design of the postbuckling response of variable angle tow composite structures
is an important consideration for future lightweight, high-performing structures. Based on this …

The paper deals with two main advantages in the analysis of slender elastic structures both
achieved through the mixed (stress and displacement) format with respect to the more …

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 objective of this study was to investigate the influence of eccentric compressive load on
the buckling, post-buckling and load-carrying capacity of thin-walled top-hat cross-section …

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 …

A numerical stochastic strategy for optimising composite elastic shells undergoing buckling
is presented. Its scope is to search for the best stacking sequence that maximises the …

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 …
