Hypo-elasticity, Cauchy-elasticity, corotational stability and monotonicity in the logarithmic strain
Patrizio Neff, Sebastian Holthausen, Marco Valerio d'Agostino +4
We combine the rate-formulation for the objective, corotational Zaremba-Jaumann rate \begin{align} \frac{{\rm D}^{\rm ZJ}}{{\rm D} t} [σ] = \mathbb{H}^{\rm ZJ}(σ).D, \qquad D = {\r…
A constitutive condition for idealized isotropic Cauchy elasticity involving the logarithmic strain
Marco Valerio d'Agostino, Sebastian Holthausen, Davide Bernardini +4
Following Hill and Leblond, the aim of our work is to show, for isotropic nonlinear elasticity, a relation between the corotational Zaremba-Jaumann objective derivative of the Cauc…
Boundary and interface conditions in the relaxed micromorphic model: exploring finite-size metastructures for elastic wave control
Gianluca Rizzi, Marco Valerio d'Agostino, Patrizio Neff +1
In this paper, we establish well-posed boundary and interface conditions for the relaxed micromorphic model that are able to unveil the scattering response of fully finite-size met…
Identification of scale-independent material parameters in the relaxed micromorphic model through model-adapted first order homogenization
Patrizio Neff, Bernhard Eidel, Marco Valerio d'Agostino +1
We rigorously determine the scale-independent short range elastic parameters in the relaxed micromorphic generalized continuum model for a given periodic microstructure. This is do…
Relaxed micromorphic broadband scattering for finite-size meta-structures -- a detailed development
Alexios Aivaliotis, Domenico Tallarico, Marco-Valerio D'Agostino +3
The conception of new metamaterials showing unorthodox behaviors with respect to elastic wavepropagation has become possible in recent years thanks to powerful dynamical homogeniza…
Relaxed micromorphic model of transient wave propagation in anisotropic band-gap metastructures
Gabriele Barbagallo, Domenico Tallarico, Marco Valerio D'Agostino +3
In this paper, we show that the transient waveforms arising from several localised pulses in a micro-structured material can be reproduced by a corresponding generalised continuum…
