We critically review and compare fifteen mixed and mixed-hybrid nonlinear shell finite
element formulations with 4 nodes in order to identify those that are closest to the “optimal” …

Unanchored steel storage tanks are used in industrial plants to store oil and other
petrochemical liquids. In a major earthquake, such tanks may sustain different types of …

Buckling and wrinkling of thin structures often lead to very complex response curves that are
hard to follow by standard path-following techniques, especially for very thin membranes in …

We show that for the simulation of crack propagation in quasi-brittle, two-dimensional solids,
very good results can be obtained with an embedded strong discontinuity quadrilateral finite …

The paper is devoted to non-linear vibrations of plates, made of the Zener viscoelastic
material modelled with the Caputo fractional derivative, and in particular to their response to …

Many shape memory alloy (SMA) applications, such as biomedical devices,
electromechanical actuators, and elastocaloric cooling devices, are based on thin-walled flat …

In continuation of our previous work on nonlinear stability analysis of trimmed isogeometric
thin shells, this contribution is an extension to dynamic buckling analyses for predicting …

This work develops a simple finite element for the geometrically exact analysis of Bernoulli–
Euler rods. Transversal shear deformation is not accounted for. Energetically conjugated …

We derive a finite element formulation for modelling fracture in 2d quasi-brittle solids. The
kinematics of isoparametric quadrilateral is enriched by strong discontinuity in …

Shell buckling process is studied by implicit structural dynamics time-stepping schemes with
numerical dissipation (in the high-frequency range), which fall into the class of Generalized …
