Simulation of shear bands using polygonal particles
نویسنده
چکیده
The choice of particle shape representation is critical in the accuracy of the simulations of real granular materials. Here we present a method to simulate particle shape using polygonal particles. The method reproduces shear bands using different boundary conditions: confining walls, floppy boundaries and periodic boundary conditions.

In some natural events such as soil failure the deformations are localized in narrow restrictions, which are called shear bands. This event which is a fundamental phenomenon in granular material, has been widely investigated during recent decades within expensive experimental tests and also some numerical simulations. Most of previously used numerical methods are based on continuum theories des...
متن کاملMicromechanical Investigation of Soil Plasticity Using a Discrete Model of Polygonal Particles
The mechanical behavior of soils has been traditionally described using continuum-mechanics-based models. These are empirical relations based on laboratory tests of soil specimens. The investigation of the soils at the grain scale using discrete element models has become possible in recent years. These models have provided valuable understanding of many micromechanical aspects of soil deformati...
متن کاملComparison of the effects of rolling resistance and angularity in sheared granular media
In this paper, we compare the effect of rolling resistance at the contacts in granular systems composed of disks with the effect of angularity in granular systems composed of regular polygonal particles. For this purpose, we use contact dynamics simulations. By means of a simple shear numerical device, we investigate the mechanical behavior of these materials in the steady state in terms of she...

-This paper presents an investigation of comminution mechanisms and microstructure development within simulated fault gouge. We sheared 4.0 mm thick layers of quartz sand between rough steel surfaces using a triaxial apparatus. The layers were sheared at constant effective normal stress of 100 MPa, under saturated drained conditions, and at 45 ° to the axis of cylindrical steel samples. Porosit...
متن کاملFluid Induced Particle Size Segregation in Sheared GranularAssembliesSitangshu
We perform a two-dimensional molecular-dynamics study of a model for sheared bidisperse granular systems under conditions of simple shear and Poiseuille ow. We propose a mechanism for particle-size segregation based on the observation that segregation occurs if the viscous length scale introduced by a liquid in the system is smaller than of the order of the particle size. We show that the ratio...
