According to the acoustic fluidization hypothesis, elastic waves at a characteristic frequency
form inside seismic faults even in the absence of an external perturbation. These waves are …

The unexpected weakness of some faults has been attributed to the emergence of acoustic
waves that promote failure by reducing the confining pressure through a mechanism known …

The frictional properties of disordered systems are affected by external perturbations. These
perturbations usually weaken the system by reducing the macroscopic friction coefficient …

We perform numerical simulations of a two-dimensional bidisperse granular packing
subjected to both a static confining pressure and a sinusoidal dynamic forcing applied by a …

Understanding the mechanisms behind the remote triggering of landslides by seismic waves
at micro-strain amplitude is essential for quantifying seismic hazards. Granular materials …

We report the simultaneous softening and compaction of a confined dense granular pack in
acoustic resonance experiments. Elastic softening is manifested by a reduction of the shear …

In this talk, we will describe quantitatively the irreversible interaction between sound and the
granular medium under low confining pressure (< 0.1 MPa). Both resonance measurement …

Dynamics of granular media is the key to understanding behavior of many natural systems.
In this work we concentrate on studying regularities of deformation of a gouge-filled fault …

Unexpectedly, granular materials can fail, the structure even destroyed, spontaneously in
simple isotropic compression with stick-slip-like frictional behaviour. This extreme behaviour …

Granular flows triggered by vibration below the avalanche angle are ubiquitous in nature.
However, the mechanism of triggering and the nature of the resulting flow are not fully …
