Several Fundamental Issues in the Mechanics of Inelastic Behavior.
Abstract
This is a final report and note of thanks to you and ONR for the support of research that began in 1987 and continued through to 1993 with a three year no additional cost extension. As you know, I was the Honorary Chair of the International Symposium on Plasticity and its Current Applications to be held in Baltimore July 19-23 and presented two papers that summarized two lines of my individual endeavor under ONR sponsorship. One was an extension of my earlier published work (Lee Anniversary Volume) on the microstructural features that control the flow strength of ductile metals and alloys. The other was an explanation of why, in a useful constitutive relation, it is necessary to define a plastic strain rate or increment that is not the rate of change or increment of whatever quantity may appeal to an author as an appropriate measure of finite plastic strain. Such a definition mirrors the accepted and necessary usage in fluid mechanics of the rate of deformation, a quantity which does not integrate over time to the finite deformation of the fluid.
