A type of prefailure instability which occurs under fully drained conditions is studied in this
paper. It is observed experimentally that when a specimen is sheared along a drained stress …

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 …

Presented here is a numerical method able to predict the mechanical behaviour of granular
materials subjected to particle removal. The purpose of this study is to improve …

The influence of three loading paths on the collapse of loose sand is analyzed with a
particular attention paid to the onset of collapse and the mode of failure exhibited …

The mechanism of flow liquefaction in granular soils under drained conditions compared
with that under undrained conditions is a subject of great interest. This paper discusses the …

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 …

Failures by divergence instabilities in rate-independent non-associated material, such as
granular matter, can occur from mechanical states described by the plastic stress limit …

Failure in soils and the yielding mechanisms involved are essential to many civil
engineering issues such as slope stability. Sudden collapse affecting slopes can be …

Granular assemblies are an illustrative example of complex material where unexpected
macroscopic properties may emerge when they are subjected to a given loading. The …

A GPU-based two-dimensional discrete element methodology allowing for grain rolling
resistance is adopted to study the engineering and fundamental aspects of shear band …
