Talk Title: Understanding Materials Dynamics under Rapid Impulsive Loading

Abstract:

Dynamic compression experiments (~5 to 200 GPa) subject materials to large compressions, deformations, and high temperatures on very short time scales (ps to μs) resulting in a rich array of physical and chemical changes. Credibly linking and understanding the dynamic response of materials in real-time across different length scales constitutes the major scientific challenge in the field. After a brief introduction about shock wave compression, this talk will summarize recent research activities, experimental developments, and future opportunities to understand condensed matter dynamics at high stresses and short times.

Refreshments will be served at 3:15 pm.

Biography: Yogendra M. Gupta, Regents Professor in the Department of Physics and Director of the Institute for Shock Physics, has been a faculty member at Washington State University (WSU) since 1981. Prior to his appointment at WSU, he spent nearly seven years at the Stanford Research Institute (now SRI International) preceded by two years of postdoctoral research. Since 1970, Gupta has been engaged in experimental and theoretical research related to shock wave and high pressure compression of condensed matter. His work has emphasized real-time examination and understanding of microscopic processes using a variety of time-resolved measurements and related analyses (optical spectroscopy, x-ray diffraction, and several continuum methods) in a wide range of materials. Gupta and his collaborators have worked on a broad range of condensed matter phenomena: structural transformations, chemical reactions, and deformation and fracture. These studies have resulted in over 275 publications. Currently, Professor Gupta is leading a major experimental effort to establish the Dynamic Compression Sector at the Advanced Photon Source (Argonne), a DOE/NNSA supported user facility. Since joining WSU, he has supervised the work of more than 100 graduate students and research associates. Professor Gupta is a Fellow of both the American Physical Society (1991) and the American Association for the Advancement of Science (2002), and has served on numerous committees related to U.S. national security programs. In 2001, he received the American Physical Society's Shock Compression Science Award, the premier award in the field. In 2005, he was the recipient of Washington State University's highest faculty recognition, the Eminent Faculty Award.
