Journal ArticleDOI
A unifying perspective: the relaxed linear micromorphic continuum
TL;DR: In this article, a relaxed linear elastic micromorphic continuum model with symmetric Cauchy force stresses and curvature contribution depending only on the micro-dislocation tensor is proposed.
Journal ArticleDOI
Wave propagation in relaxed micromorphic continua: modeling metamaterials with frequency band-gaps
TL;DR: In this paper, Ghiba et al. showed that the presence of band-gaps is related to a unique elastic coefficient, the so-called Cosserat couple modulus, which is also responsible for the loss of symmetry of the Cauchy force stress tensor.
Journal ArticleDOI
The Exponentiated Hencky-Logarithmic Strain Energy. Part I: Constitutive Issues and Rank-One Convexity
Patrizio Neff,Ionel-Dumitrel Ghiba,Ionel-Dumitrel Ghiba,Ionel-Dumitrel Ghiba,Johannes Lankeit +4 more
TL;DR: In this paper, a family of isotropic volumetric-isochoric decoupled strain energies was investigated and the rank-one convexity of these energies was shown in plane elastostatics.
Journal ArticleDOI
Wave propagation in relaxed micromorphic continua: modelling metamaterials with frequency band-gaps
TL;DR: In this article, the authors proposed a relaxed linear micromorphic model to study wave propagation in unbounded continua with microstructure and showed that the presence of band-gaps is related to a unique elastic coefficient, the so-called Cosserat couple modulus, which is also responsible for the loss of symmetry of the Cauchy force stress tensor.
Journal ArticleDOI
The relaxed linear micromorphic continuum: Existence, uniqueness and continuous dependence in dynamics
TL;DR: In this paper, a relaxed linear elastic micromorphic continuum model with symmetric Cauchy force-stresses and curvature contribution depending only on the micro-dislocation tensor is studied.
