Granular materials are the most recurrent form of solid-state matter on Earth. They challenge
researchers and engineers in various fields not only because they occur with a broad variety …

Particle morphology plays a key role in affecting physical and mechanical behaviors of
granular media. While various mathematical approaches and shape descriptors have been …

颗粒材料的宏观应力变形特征与其微观接触力, 组构等紧密相关. 一般而言, 强接触系统属于颗粒
内部体系的传力结构, 其对应的组构张量是影响宏观应力性质的重要因素. 细观数值方法(如离散 …

This paper presents a synthesis of the works performed by various teams from France, Italy
and Canada around the question of second‐order work criterion. Because of the non …

The shear band issue in frictional granular materials has attracted many concerns and
perspectives at the micro-and meso-scale have been involved to analyze this problem. At …

The concept of failure is one of the most debated in soil mechanics, for two reasons
essentially. First, this is a crucial issue in the engineering of structures and geotechnical …

Solving boundary value problems requires implementation of sufficiently robust constitutive
models. Most models try to incorporate a great deal of phenomenological ingredients, but …

This paper investigates the issue of failure in rate-independent granular material specimens
under a novel line of reasoning. The mechanism of failure is related to an increase in kinetic …

In this paper the onset of instabilities in elastoplastic materials is theoretically studied and a
conceptual basis for understanding the physical implications of a loss of uniqueness and/or …

Granular materials react under external loading by self-organizing the topology of the grain
assembly. Thus, quasi-linear grain patterns, known as force chains, develop within the …
