The exponentiated Hencky-logarithmic strain energy. Part III: Coupling with idealized isotropic finite strain plasticity
Patrizio Neff, Ionel-Dumitrel Ghiba
We investigate an immediate application in finite strain multiplicative plasticity of the family of isotropic volumetric-isochoric decoupled strain energies \begin{align*} F\mapsto…
Comparison of isotropic elasto-plastic models for the plastic metric tensor
Patrizio Neff, Ionel-Dumitrel Ghiba
We discuss in detail existing isotropic elasto-plastic models based on 6-dimensional flow rules for the positive definite plastic metric tensor and highlight thei…
Band gaps in the relaxed linear micromorphic continuum
A. Madeo, P. Neff, I. -D. Ghiba +2
In this note we show that the relaxed linear micromorphic model recently proposed by the authors can be suitably used to describe the presence of band-gaps in metamaterials with mi…
The relaxed linear micromorphic continuum: well-posedness of the static problem and relations to the gauge theory of dislocations
Patrizio Neff, Ionel-Dumitrel Ghiba, Markus Lazar +1
In this paper we consider the equilibrium problem in the relaxed linear model of micromorphic elastic materials. The basic kinematical fields of this extended continuum model are t…
