In the problem of the synthesis of metamaterials, the pantographic architecture revealed remarkable potentialities. Indeed it allowed for the synthesis of second gradient 2D (nonlinear) continua: i.e. 2D shells whose deformation energy depends also o

International audience; In this paper, we study the anisotropy classes of the fourth order elastic tensors of the relaxed micro-morphic model, also introducing their second order counterpart by using a Voigt-type vector notation. In strong contrast w

Relaxed micromorphic modeling of the interface between a homogeneous solid and a band-gap metamaterial : new perspectives towards metastructural design

In the present paper, the material parameters of the isotropic relaxed micromorphic model derived for a specific metamaterial in a previous contribution are used to model its transmission properties. Specifically, the reflection and transmission coef

First evidence of non-locality in real band-gap metamaterials: determining parameters in the relaxed micromorphic model

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, Royal Society, The, 2016, 472 (2190), ⟨10.1098/rspa.2016.0169⟩

In this paper, we propose the first estimate of some elastic parameters of the relaxed micromorphic model on the basis of real experiments of transmission of longitudinal plane waves across an interface separating a classical Cauchy material (steel p
