Role of Interfaces and Interphases in the Evolution Mechanics of Material Systems
Abstract
The general objective of this investigation is to apply the discipline of mechanics to the prediction and description of the long-term behavior of composite materials by developing experimental information, conceptual understanding, and analytical representations of the evolution of the properties of constituent materials and interfaces in composite material systems as a function of (generalized) time during the application of time-variable mechanical, thermal, and chemical loadings. The general approach to this objective is to develop mechanistic representations of the 'state of the material' under those conditions, and to join those descriptions with micromechanical descriptions of the 'state of stress' in 'critical elements' to support an estimate of remaining strength, and, thereby, to predict remaining life. We have named this enterprise 'evolution mechanics.
