Rethinking Constitutive Theories
Seminar | August 23 | 1-2 p.m. | 3110 Etcheverry Hall
Dr. K. R. Rajagopal, Distinguished Professor, Department of Mechanical Engineering, Texas A&M University
After discussing the rationale and the need for rethinking the development of constitutive relations, both from philosophical and pragmatic viewpoints, to describe the response of both non-linear fluids and solids, I will discuss the development of a new class of constitutive relations and applications wherein they can be gainfully exploited. It will be shown that the new constitutive relations can explain phenomena that have hitherto defied adequate explanation. Such models have the potential to describe the response of fluids and solids with properties that depend both on the invariants of the stress and appropriate kinematical variables.
