This session will discuss the mechanical properties of disordered materials across multiple scales while bridging the fields of metallic and nonmetallic glasses, as well as mechano-optical and mechanoelectrical couplings. We will consider the structural origin of elasticity, plasticity, and fracture with the objective of designing glasses with superior toughness, defect tolerance, and stiffness, combining mechanical and various functional properties. Particular attention shall be given to the identification of general, material-independent constitutive laws, which may be used as guidelines to improve the mechanical properties; the combination of experimental approaches and computational modeling of the stress response of glasses and early stages of damage infliction; and the interplay between size and time effects, stress corrosion, and the chemical aspect of fracture. Contributions on the following topics are especially invited.

  • Dynamic fracture and brittleness, or crack initiation, including the application of in-situ techniques
  • Slow crack growth and stress corrosion cracking, the underlying chemistry and transport phenomena in high-stress fields
  • Multiscale investigation of elasticity, plasticity, and hardness in relation to bulk topology through combining mechanical analyses with structural analyses
  • Strategies for toughening inorganic oxide glasses as well as metallic glasses
  • Mechanoelectrical and mechano-optical couplings
