Self-organization and memory in driven disordered materials

Speaker: Prof. Damien Vandembroucq (ESPCI, Paris)

Abstract:

The mechanical behavior of disordered materials such as colloidal suspensions, pastes, soft and hard glasses or fabrics depends on their thermal and mechanical history: fabrication, processing, deformation, etc. In other words, these material retain a memory of their mechanical past. In this talk we discuss self-organization and memory formation in simple mesoscopic elastoplastic models of amorphous solids. We consider different types of training and reading protocols and discuss how self-organization and memory formation of disordered materials can emerge under more general conditions, such as a disordered system interacting with its fluctuating environment.
