In this paper we model the size-effects of metamaterial beams under bending with the aid of
the relaxed micromorphic continuum. We analyze first the size-dependent bending stiffness …

The present contribution aims to revisit higher-order homogenization schemes towards
micromorphic media based on variational principles and an extension of Hill …

We determine the material parameters in the relaxed micromorphic generalized continuum
model for a given periodic microstructure in this work. This is achieved through a least …

The present contribution aims to build chiral Cosserat effective models of architectured
media prone to such effects, recoursing to dedicated homogenization methods. In order to …

Mechanical metamaterials feature engineered microstructures designed to exhibit exotic,
and often counter-intuitive, effective behaviour such as negative Poisson's ratio or negative …

Elastomeric mechanical metamaterials exhibit unconventional behaviour, emerging from
their microstructures often deforming in a highly nonlinear and unstable manner. Such …

A novel numerical strategy is developed in this article to study the free vibrations of
hyperelastic micromorphic continua under bending load. In the proposed approach, the …

We present a so-called pseudo-nonlocal eight-node fully integrated linear hexahedral
element coined as PN3D8 for finite element analysis of computationally demanding material …

Elastomeric mechanical metamaterials exhibit unconventional mechanical behaviour owing
to their complex microstructures. A clear transition in the effective properties emerges under …

The present contribution provides a classification of generalized continua constructed by a
micromechanical approach, relying on an extension of the Hill macrohomogeneity condition …
