The mechanics of the flowing granular materials such as coal, agricultural products, at deal of attention as it has fertilizers, dry chemicals, metal ores, etc. have received a great deal of attention as it has relevance to several important technological problems. Despite wide interest and more...

Humidity is well-known to significantly affect the mechanical properties, static as well as dynamic, of granular materials. We present the method of humidification of granular media from an under-saturated vapor that we designed in order to experimentally quantify such moisture-induced effects...

We report sets of precise and reproducible measurements on the static pressure at the bottom of a granular column. We make a quantitative analysis of the pressure saturation when the column height is increased. We evidence a great sensitivity of the measurements with the global packing fraction...

Granular systems show a pronounced deviation from classical Boltzmann statistics of several aspects. In particular, we review some findings on anomalous velocity distributions.

An independent-collision model is advanced as a conceptually simple and computationally convenient framework for understanding non-linear impulse propagation in granular chains. In particular, conservation principles are used to show that the independent-collision model supports solitons in...

We bring out the salient characteristics displayed by grain avalanches in laboratory experiments. We devise then elementary mechanisms accounting for these main features and we derive a modeling capable of capturing the nonlocal processes relevant to the avalanche expansion. The growth patterns...

A recent theory for stress transmission in isostatic granular and cellular systems predicts a constitutive equation that couples the stress field to the local microstructure (Phys. Rev. Lett. 88 (2002) 115505). The theory could not be applied to macroscopic systems because the constitutive...

This paper presents techniques and algorithms to compute microstructure properties of irregular-shaped granulate assemblies utilizing 3D images. The techniques are capable of extracting microstructure properties of particles such as centeroid, particle size distribution, shape indices (i.e.,...
