The aim of this paper is to test a simple damage model of a cohesive granular medium to study the relationship between the damage and velocity of elastic waves. Our numerical experiments of edometric compression show that the microscopic deformation

We study the transition from cohesive to noncohesive granular states of synthetic rocks under oedometric loading, combining simultaneous measurements of ultrasound velocity and acoustic emissions. Our samples are agglomerates made of glass beads bond

The damage and the resulting cohesion of the rocks control the slip and the earthquakes nucleation. This phenomenon is not well understood, that is why we are interested in the interplay between friction in the fault and damage of the surrounding vol

International audience; Earthquakes or fault core sliding occur naturally in response to long-term deformation produced by plate tectonics. The way the damage or fracture process of rocks control the frictional slip is not well understood. It involve

We study the transition from cohesive to granular-like states of synthetic rocks under external loading by ultrasound velocity measurements and acoustic emission detections. Our model rocks are made of glass beads bonded with a few percent of cements
