Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

Granular materials consist of macroscopic grains, interacting via contact forces, and
unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, ie …

颗粒流是高速远程滑坡物质演化过程的一个重要阶段, 也是从细观角度揭示其超常运动特性的
重要手段. 颗粒流所采用的主要研究方法以及取得的重要理论成果, 可以为高速远程滑坡动力学 …

The behaviour of dense assemblies of dry grains submitted to continuous shear deformation
has been the subject of many experiments and discrete particle simulations. This paper is a …

We review flows of dense cohesionless granular materials, with a special focus on the
question of constitutive equations. We first discuss the existence of a dense flow regime …

Experiments on a slowly sheared 2D granular material show a continuous transition as the
packing fraction γ passes through γ c≃ 0.776. The mean stress, σ, plays the role of an order …

Photoelastic techniques are used to make both qualitative and quantitative measurements of
the forces within idealized granular materials. The method is based on placing a birefringent …

We study the scheme of formal arcs on a singular algebraic variety and its images under
truncations. We prove a rationality result for the Poincare series of these images which is an …

Granular materials and ordinary fluids react differently to shear stresses. Rather than
deforming uniformly, materials such as dry sand or cohesionless powders develop shear …

A review of measurements and atomistic modeling shows that shear bands in metallic
glasses have a characteristic thickness of∼ 10 nm⁠. Such extreme localization of plastic …
