Mechanical Deformation of Glassy Solids: Why Structural Engineers Need New Ideas in Nonequilibrium Physics

James Langer
University of California at Santa Barbara

Glassy materials, and noncrystalline materials in general, make up a very large part of our world, yet we have no deep fundamental understanding of them. Despite the fact that glasses look microscopically very much like fluids, we have no fluidlike equations of motion with which to predict how they will perform in practical applications. In this lecture, I will talk about recent developments in the theory of glassy rheology, and the emerging concept of an effective temperature as a useful way to describe the dynamics of internal disorder in noncrystalline materials. Applications to be discussed include deformation of bulk metallic glasses, and shear failure in the lab and in earthquake faults.
