The stress–strain behaviour of granular materials can be modelled with hypoplastic
constitutive relations. A hypoplastic model is briefly introduced for the axially symmetric …

Cet article traite de l'érosion due à l'infiltration menant aux processus de liquéfaction et aux
ruptures rapides de talus. L'on présente une histoire de cas qui s' est produit le long d'une …

Features of rheological laws applied to solid-like granular materials are recalled and
confronted to microscopic approaches via discrete numerical simulations. We give examples …

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 …

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 constant shear drained (CSD) test is considered an appropriate test to simulate the
instability behavior of soils in slopes under water infiltration conditions or lateral stress relief …

Within the framework of the second‐order work theory, the onset of instabilities is explored
numerically in loose granular materials through three‐dimensional DEM simulations. Stress …

The problem of mechanical instability of loose sand specimens during drained load
controlled triaxial compression tests (creep tests) is discussed. In order to model …

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 …
