Advection-diffusion in porous media with low scale separation: modelling via higher-order asymptotic homogenisation
Pascale Royer
Asymptotic multiple scale homogenisation allows to determine the effective behaviour of a porous medium by starting from the pore-scale description, when there is a large separatio…
Force chains and contact network topology in packings of elongated particles
Émilien Azema, Farhang Radjaï
By means of contact dynamic simulations, we investigate the contact network topology and force chains in two-dimensional packings of elongated particles modeled by rounded-cap rect…
Simulation nnnumérique discrète et comportement mécanique des matériaux granulaires
Jean-Noël Roux, François Chevoir
As a complementary tool to laboratory experiments, discrete numerical simulation, applied to granular materials, provides valuable information on the grain and contact scale micros…
Sound wave velocities in dry and lubricated granular packings packings: numerical simulations and experiments
Ivana Agnolin, Jean-Noël Roux, Pascal Massaad +2
Numerical simulations are used to investigate the origins of the different wave velocities measured in dense granular samples assembled with different methods. Glass bead packings…
Quasistatic behavior and force transmission in packing of irregular polyhedral particles
Émilien Azema, Farhang Radjaï, Gilles Saussine
Dense packings composed of irregular polyhedral particles are investigated by numerical simulations under quasistatic triaxial compression. The Contact Dynamics method is used for…
Quasistatic rheology, force transmission and fabric properties of a packing of irregular polyhedral particles
Émilien Azema, F. RadjaÏ, G. Saussine
By means of contact dynamics simulations, we investigate a dense packing composed of polyhedral particles under quasistatic shearing. The effect of particle shape is analyzed by co…
Transmission des forces dans un milieu composé de grains non sphériques
Émilien Azema, F. RadjaÏ, R. Peyroux +1
We perform a detailed analysis of the contact force network in a dense confined packing of pentagonal particles simulated by means of the contact dynamics method. The effect of par…
Force transmission in a packing of pentagonal particles
Émilien Azema, Farhang Radjai, Robert Peyroux +1
We perform a detailed analysis of the contact force network in a dense confined packing of pentagonal particles simulated by means of the contact dynamics method. The effect of par…
Coherent thermodynamical modelling of geomaterial reinforced by wires
Romain Laniel, Pierre Alart, Stéphane Pagano
The TexSol is a composite geomaterial : a sand matrix and a wire network reinforcement. For small strains a thermodynamical continuous model of the TexSol including the unilaterali…
Vibrational dynamics of confined granular material
Emilien Azema, Farhang Radjaï, Robert Peyroux +2
By means of two-dimensional contact dynamics simulations, we analyze the vibrational dynamics of a confined granular layer in response to harmonic forcing. We use irregular polygon…
Modélisation des déformations de maturation de la fibre
François Sassus, Tancrède Alméras, Joseph Gril +1
The generation mechanism of growth strains is investigated theoretically by developing an elastic analysis of a wood cell viewed as a composite tube, with layers composed of a lign…
Role of the Gelatinous Layer (G-Layer) on the Origin of the Physical Properties of the Tension Wood of Acer sieboldianum
Hiroyuki Yamamoto, Kentaro Abe, Yoshiharu Arakawa +2
The tension wood (TW) properties of a 70 year-old Acer sieboldianum Miq were analyzed by using the G-fiber model which was proposed in our previous paper. The roles of the G-layer…
Reduction of wood hygroscopicity and associated dimensional response by repeated humidity cycles
Luis García Esteban, Joseph Gril, Paloma De Palacios De Palacios +1
The reduction of wood response to variations of ambient humidity, described as kind of ageing, has been studied from both points of view of moisture uptake and dimensional changes.…
Self-stresses and Crack Formation by Particle Swelling in Cohesive Granular Media
Moulay Said El Youssoufi, Jean-Yves Delenne, Farhang Radjai
We present a molecular dynamics study of force patterns, tensile strength and crack formation in a cohesive granular model where the particles are subjected to swelling or shrinkag…
