Scope

The large-scale behavior of materials often stems from a combination of effects that emerge across many scales in space and time. In particular, irreversible deformation – such as plasticity and fracture – involves long-range interactions and atomistic effects. The resulting physics exhibits cooperative phenomena that have started only recently to be appreciated. In this symposium we convene speakers that address the whole spectrum of associated ideas, from recent experimental advances that call for a statistical analysis to effective models of fluctuation phenomena and coarse-grained laws of irreversible deformation. List of topics to be addressed in the symposium include:

• Statistical methods for multiscale models.
• Statistical analysis of experimental data: crack surfaces, acoustic emission, deformation curves.
• Statistical models for fracture and plasticity at the mesoscale.
• Interacting dislocation systems: avalanches, pattern formation.
• Irreversible deformation of non crystalline solids: amorphous solids, glasses, granular media.
• Plasticity of non conventional crystals: vortex lattice, colloidal crystals.
• Non-linear elasticity, non-affine responses and soft modes.
