During the past decades, notable improvements have been achieved in the understanding
of static and dynamic properties of granular materials, giving rise to appealing new concepts …

We present an experimental study of jamming in the discharge of grains through an opening
in a two-dimensional silo. For a wide range of outlet sizes, we obtain the size distribution of …

We present experimental results obtained with a two-dimensional silo discharging under
gravity through an orifice at the flat bottom. High-speed measurements provide enough time …

We study the discharge of a two-dimensional silo through small openings via discrete
element simulations. We consider the effect of the shape of the grains on the clogging of the …

365 revealed by the different nature of their statistical properties. In the following sections we
will deep into this question and others, such as the arguments on the existence or not of a …

A group of competitive people esca** through an exit could lead to the formation of a
deadlock, which significantly increases the evacuation time. Such a phenomenon is called …

The faster-is-slower effect (FIS), which means that crowd at a high enough velocity could
significantly increase the evacuation time to escape through an exit, is an interesting …

Simulations of a polydispersed two-dimensional silo were performed using molecular
dynamics, with different numbers of grains reaching up to 64 000, verifying numerically the …

Crowd force by the pushing or crushing of people has resulted in a number of accidents in
recent decades. The aftermath investigations have shown that the physical interaction of a …

Binary mixtures of dry grains avalanching down a slope are experimentally studied to
determine the interaction among coarse and fine grains and their effect on the morphology …
