Research on the structural behavior and buckling of vertical, aboveground tanks employed
to store oil and fuels have significantly increased during the past two decades. Interest in this …

The precision forming of thin-walled components has been urgently needed in aviation and
aerospace field. However, the wrinkling induced by the compressive instability is one of the …

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 …

Mechanical metamaterials such as open‐and closed‐cell lattice structures, foams,
composites, and so forth can often be parametrized in terms of their microstructural …

Finite element asymptotic post-buckling analysis, being based on fourth-order expansions of
the strain energy, requires that nonlinear structural modeling be accurate to same order, at …

This paper revisits the buckling analysis of a benchmark cylindrical panel undergoing snap-
through when subjected to transverse loads. We show that previous studies either …

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 …

Variable-stiffness shells are curved composite structures in which the fibre-reinforcement
follow curvilinear paths in space. Having a wider design space than traditional composite …

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 …

A sequential nonlinear multiscale method for the simulation of elastic metamaterials subject
to large deformations and instabilities is proposed. For the finite strain homogenization of …
