Session 5: Mechanical Properties of Glasses
This session will discuss the mechanical properties of disordered materials on a multiscale level, bridging the fields of metallic and nonmetallic glasses. We will consider the structural origin of elasticity, plasticity, and fracture with the objective of designing glasses with superior toughness, defect tolerance, and stiffness. Particular attention shall be given to the identification of general, material-independent constitutional laws which may act as levers for controlling 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 are especially invited on:
- Dynamic fracture and brittleness, including the application of in-situ techniques
- Subcritical fracture and stress corrosion, 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
The session is partially supported by the priority program 1594 “Topological Engineering of Ultrastrong Glasses” of the German Science Foundation. A limited number of travel grants are available for Ph.D. students, subject to individual application.
