Solid State Seminar, Spring 2002
Department of Physics, OSU

Solid State Seminars are on Wednesdays, from 4:00 pm to 5:00 pm in Weniger 287, unless otherwise noted. This term, the seminar series is organized by Janet Tate, to whom any comments and suggestions about the series should be sent. The Solid State Seminar is generally followed by a "Liquid State Seminar" at Clodfelters,the local watering hole on Monroe Street. Everyone is welcome.

Thermoelastic Fluctuations in Solids, Dr. Padmaja Akkaraju

The inter-relationship between the mechanical work done on a material in the elastic range and changes in its thermodynamic properties is known as the thermoelastic effect, a phenomenon that is of great interest to geophysicists as well as mechanical engineers. I will present an overview of the recent experimental and theoretical research, and will review our work that led to a thorough analysis of the thermoelastic fluctuations in solids. I will discuss the applications of our theory to study thermoelasticity in various materials subjected to compressive and unidirectional stresses. This project is a joint work with Dr. T.H.K. Barron, Department of Theoretical Chemistry, University of Bristol, UK. (return)
