Symposium description

This symposium will bring together researchers working on theory, simulation, and experiments on the mechanical properties of amorphous solids.  Materials of interest include metallic and polymeric glasses and soft glassy matter (glassy suspensions, emulsions, foams, granular matter etc.).  The methods used to understand these systems include: direct particle-scale simulations, coarse-grained models based on a picture of localized plastic shear transformations, and continuum models based on the statistical physics of elementary yielding events such as shear transformation zone theory, the soft glassy rheology model, and models based on ideas of facilitated dynamics and fluidity. Recent experimental advances, among other things, have allowed for: microscopic visualization of elementary rearrangement processes and shear localization in colloidal glasses, ultrasonic measurements of elastic properties of glasses and supercooled liquids, mechanical measurements of individual slip avalanches along shear bands in metallic glasses during plastic flow, development of new metallic glasses with improved fracture toughness and stability.

Abstracts are invited for the following broad themes, which cut across these materials systems:

  • Characterization of particle-scale rearrangements, local structure, and relation to mechanical response
  • Avalanches, critical behavior at the yielding transition, and localization
  • Memory, creep, and yielding
  • Mesoscopic models: specific ingredients and emergent behaviors
  • Continuum models of yielding, shear localization, flow in confined geometries, and fracture.
