Frictional weakening induced by cohesion: the numerical case of cohesive granular failures
Lydie Staron, Laurent Duchemin, Anais Abramian +1
The failure of 2D numerical cohesive granular steps collapsing under gravity are simulated for a large range of cohesion. Focussing on the cumulative displacement of the grains, an…
Small Solar System Bodies as granular media
D. Hestroffer, P. Sánchez, L. Staron +12
Asteroids and other Small Solar System Bodies (SSSBs) are of high general and scientific interest in many aspects. The origin, formation, and evolution of our Solar System (and oth…
Stress partition and micro-structure in size-segregating granular flows
L. Staron, J. C. Phillips
When a granular mixture involving grains of different sizes is shaken, sheared, mixed, or left to flow, grains tend to separate by sizes in a process known as size segregation. In…
Continuum simulation of the discharge of the granular silo: a validation test for the mu(I)-visco-plastic flow law
L. Staron, P. -Y. Lagrée, S. Popinet
Using both a continuum Navier-Stokes solver, with the mu(I)-flow-law implemented to model the viscous behavior, and the discrete Contact Dynamics algorithm, the discharge of granul…
Friction and the oscillatory motion of granular flows
Lydie Staron
This contribution reports on numerical simulations of 2D granular flows on erodible beds. The broad aim is to investigate whether simple flows of model granular matter exhibits spo…
The granular silo as a continuum plastic flow: the hour-glass vs the clepsydra
Lydie Staron, Pierre-Yves Lagrée, Stéphane Popinet
The granular silo is one of the many interesting illustrations of the thixotropic property of granular matter: a rapid flow develops at the outlet, propagating upwards through a de…
