Metamaterials are materials especially engineered to have a peculiar physical behaviour, to
be exploited for some well-specified technological application. In this context we focus on …

In this paper we present a model in which the motions of two families of beams constituting a
pantographic sheet, when described with two independent placement fields, allows to …

In this paper we consider a two-degrees-of-freedom, non-linear model aiming to describe
internal friction phenomena which have been observed in some modified concrete …

Torsion and shear stress fields of a Saint-Venant beam and the relative location of shear
and twist centres are investigated for sections of any degree of connectedness. The sliding …

In the present paper, a constitutive model for the description of the dissipation in the
concrete is provided. The theoretical description is based on a micromorphic model in which …

A beam model aimed at describing the flexural–torsional buckling of thin-walled members
with non-symmetric cross-sections is presented. Two beam axes are introduced, and strain …

The relationship between twist and shear centres in an orthotropic Saint–Venant beam, with
fiberwise homogeneous elastic moduli and constant Poisson ratios, is investigated. Arbitrary …

In this paper, the direct one-dimensional beam model introduced by one of the authors is
refined to take into account nonsymmetrical beam cross-sections. Two different beam axes …

We illustrate the consistent derivation of a one-dimensional (1D) beam model from the Saint
Venant three-dimensional (3D) solution of a beam-like solid that aims at the formulation of a …

Torsion and bending/torsion buckling may occur for compressed thin-walled open profiles
used in engineering and architecture applications. We report experimental results provided …
