A database of the mechanical behavior of 25 natural sands was compiled from the existing
literature. Particle shape and size analysis, obtained by dynamic imaging analysis, for each …

Fold-and-thrust belts and accretionary wedges form by compression of sedimentary
sequences and basement rocks into forward and backward thrusts, folds, nappes, and …

A new constitutive model is introduced which is formulated in the framework of classical
theory of plasticity. In the model the total strains are calculated using a stress-dependent …

To simulate debris-flow behaviour from initiation to deposition, we derive a depth-averaged,
two-phase model that combines concepts of critical-state soil mechanics, grain-flow …

This paper aims at analyzing the influence of non-associated flow rule on passive face
instability for shallow shield tunnels. The influence exerted by dilation angle on the limit …

The properties of clean sands pertaining to shear strength and stiffness have been studied
extensively. However, natural sands generally contain significant amounts of silt and/or clay …

Simulation of geodynamic processes in sandbox experiments requires analogue materials
with a deformation behaviour that reproduces the deformation mechanisms of typical crustal …

Large cyclic loading on ballasted railroad tracks is now inevitable owing to an increased
demand for freight and public transport. This leads to a progressive deterioration and …

Soils are particulate materials. Therefore, the behavior of soils is determined by the forces
particles experience. These include forces due to boundary loads (transmitted through the …

Particulate materials, such as sandy soil, are everywhere in nature and form the basis for
many engineering applications. The aim of this research is to investigate the particle shape …
