Dr. Kaushik Bhattacharya, Vice Provost, Howell N. Tyson Sr. Professor of Mechanics & Materials Science, California Institute of Technology: "Can You Print Your Toughness?"
Recent advances in material synthesis enable us to control material microstructure with unprecedented detail. This talk explores whether this ability can be exploited to create materials with unprecedented properties. Of particular interest are phenomena like fracture, dislocation dynamics, phase boundary propagation and peeling that are governed by the evolution of a free boundary or free discontinuity. In these phenomena, the effective behavior is not characterized by averaging, but instead dominated by critical events. Thus, the effective behavior can be qualitatively different from the local behavior. This talk will explore these issues with selected examples.
