A polyconvex extension of the logarithmic Hencky strain energy
Robert J. Martin, Ionel-Dumitrel Ghiba, Patrizio Neff
Adapting a method introduced by Ball, Muite, Schryvers and Tirry, we construct a polyconvex isotropic energy function which is equal to…

Effective description of anisotropic wave dispersion in mechanical band-gap metamaterials via the relaxed micromorphic model
Marco Valerio d'Agostino, Gabriele Barbagallo, Ionel-Dumitrel Ghiba +3
In this paper the relaxed micromorphic material model for anisotropic elasticity is used to describe the dynamical behavior of a band-gap metamaterial with tetragonal symmetry. Unl…
