Water transfer and crack regimes in nano-colloidal gels
J Thiery, Stéphane Rodts, E Keita +5
Direct observations of the surface and shape of model nano-colloidal gels associated with measurements of the spatial distribution of water content during drying show that air star…
Coupling a reactive potential with a harmonic approximation for atomistic simulations of material failure
Ignacio Tejada, Laurent Brochard, Tony Lelievre +3
Molecular dynamics (MD) simulations involving reactive potentials can be used to model material failure. The empirical potentials which are used in such simulations are able to ada…
Special Quasirandom Structures: a selection approach for stochastic homogenization
Claude Le Bris, Frederic Legoll, William Minvielle
We adapt and study a variance reduction approach for the homogenization of elliptic equations in divergence form. The approach, borrowed from atomistic simulations and solid-state…
Mollification in strongly Lipschitz domains with application to continuous and discrete De Rham complex
Alexandre Ern, Jean-Luc Guermond
We construct mollification operators in strongly Lipschitz domains that do not invoke non-trivial extensions, are stable for any real number , and commute wit…
Flow of wet granular materials: a numerical study
Saeed Khamseh, Jean-Noël Roux, François Chevoir
We simulate dense assemblies of frictional spherical grains in steady shear flow under controlled normal stress in the presence of a small amount of an interstitial liquid, whi…
Optimization of gridshell bar orientation using a simplified genetic approach
Lina Bouhaya, Olivier Baverel, Jean-François Caron
Gridshells are defined as structures that have the shape and rigidity of a double curvature shell but consist of a grid instead of a continuous surface. This study concerns those o…
