Vorticity-dependent and symmetry-preserving LES models
Oscar Cosserat, Dina Razafindralandy, Can Selçuk
Within the Large Eddy Simulation framework, we propose a methodology based on the Lie theory to derive symmetry-preserving turbulence models. We apply this methodology to the incom…
Adjoint-based optimization of two-dimensional Stefan problems
Tomas Fullana, Vincent Le Chenadec, Taraneh Sayadi
A range of optimization cases of two-dimensional Stefan problems, solved using a tracking-type cost-functional, is presented. A level set method is used to capture the interface be…
Explicit Harmonic Structure Of Bidimensional Linear Strain-Gradient Elasticity
Nicolas Auffray, Houssam Andoul-Anziz, Boris Desmorat
In the perspective of homogenization theory, strain-gradient elasticity is a strategy to describe the overall behaviour of materials with coarse mesostructure. In this approach, th…
A minimal integrity basis for the elasticity tensor
Nicolas Auffray, Marc Olive, Boris Kolev
We definitively solve the old problem of finding a minimal integrity basis of polynomial invariants of the fourth-order elasticity tensor C. Decomposing C into its SO(3)-irreducibl…
Reflection and transmission of elastic waves at interfaces embedded in non-local band-gap metamaterials: a comprehensive study via the relaxed micromorphic model
Angela Madeo, Patrizio Neff, Ionel-Dumitrel Ghiba +1
In this paper we derive, by means of a suitable least action principle, the duality jump conditions to be imposed at surfaces of discontinuity of the material properties in non-dis…
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…
