Numerical issues in plasticitymodels for granular flows
نویسنده
چکیده
Friction plays a fundamental role in the Mechanics of granular materials. Two problems are considered: (i) heap formation, (ii) granular flow. Both problems admit closely related mathematical models. In each case, analytical and numerical difficulties are discussed. Efficient and reliable numerical methods are proposed and implemented. The results are illustrated by several computational experiments.

Numerical Simulation of Granular Column Collapses with Pressure-Dependent Viscoplastic Model using the Smoothed Particle Hydrodynamic Method
This paper presents a numerical analysis of granular column collapse phenomenon using a two-dimensional smoothed particle hydrodynamics model and a local constitutive law proposed by Jop et al. This constitutive law, which is based on the viscoplastic behaviour of dense granular material flows, is characterized by an apparent viscosity depending both on the local strain rate and the local press...
متن کاملCollisional Granular Flows with and without Gas Interactions in Microgravity
We illustrate the convenience of a long-lasting microgravity environment to study flows of granular materials with and without gas interaction. We consider collisional granular flows of nearly elastic identical spheres in an axisymmetric Couette channel featuring two cylindrical moving bumpy boundaries and two flat walls. We review governing equations for these flows, illustrate their solutions...
متن کاملA new constitutive law for dense granular flows
In many geophysical or industrial applications involving flows of grains, a continuum description would be of considerable help, for example in predicting natural hazards or in designing industrial processes. However, constitutive equations for dry granular flows are still matter of debates 1-10. One difficulty is that grains can behave like a solid (in a sand pile), a liquid (when poured from ...
متن کاملGravity-driven granular free-surface flow around a circular cylinder
Snow avalanches and other hazardous geophysical granular flows, such as debris flows, lahars and pyroclastic flows, often impact on obstacles as they flow down a slope, generating rapid changes in the flow height and velocity in their vicinity. It is important to understand how a granular material flows around such obstacles to improve the design of deflecting and catching dams, and to correctl...
متن کاملModelling and numerical aspects of fluid-saturated granular materials: application to shear flows
Introduction: In the first part of this talk, we present an algorithm for the numerical treatment of twopressure, two velocity continuum models for heterogeneous, immiscible mixtures [1]. This algorithm has been employed in a numerical study of unsteady shear flows of fluid-saturated granular materials, as predicted by the continuum model of [2]. A representative sample of these results are pre...
