Mechanics Models for Strength and Durability of Fiber-Reinforced Ceramic and Polymer Composites

Abstract

New advances in the field of multiscale modeling of the tensile strength and time-dependent failure behavior of fiber reinforced composites are described. The major accomplishments include the development of a methodology for extracting information from finite element studies at the scale of a few fibers and using this information in a flexible Green's function model to compute damage evolution and failure in the composite. Recent work as aimed at developing models to predict composite electrical resistance as a function of mechanical damage so that electrical resistance measurement of in-service components can be used as an on-board health-monitoring system.
