Memory effects in mesoscopic elasto-plastic models of amorphou solids

Due to their out-of-equilibrium nature, materials such as amorphous solids, glasses or dense suspensions exhibit a history-dependent mechanical behavior. Thermal and mechanical annealing drastically affect the modes of deformation and failure. In recent years experiments and numerical simulations of disordered materials under cyclic loading have unveiled puzzling properties such as the convergence to reversible plastic cycles or the possibility to record and read a past state of deformation. We give a short review of such memory effects in lattice-based elastoplastic models of amorphous solids.
