Disordered materials—such as glasses, colloids, foams, biological tissues—exhibit complex mechanical response with pronounced history-dependence. These systems show striking phenomena including yielding transitions, avalanches, localization of flow, and memory effects. While these behaviors are now broadly recognized, their physical origins and universal principles remain largely open. The goal of ReMCoM is to develop a unified framework that can describe mechanical response and memory formation in these complex systems. Combining experimental, theoretical, and numerical tools, the project will address:

• How materials transition from solid-like to flowing behavior under stress

• How the history of deformation is encoded and recalled

• How training protocols can induce new mechanical functionalities.

The project brings together French and Indian researchers with complementary expertise: statistical physics and modeling (France), soft matter and biological experiments (India). Building on more than 15 years of collaboration (including two CEFIPRA projects), ReMCoM aims to establish a long-term Indo-French framework for joint research and student training.
