Abstract

The objective of this presentation is to describe experimental work that quantifies the damage and self-healing behavior of laminated fiber-reinforced polymer-matrix composites. The experimental procedures used will be explained and justified. The effects of damage, healing, unrecoverable strains (plasticity), hardening, and hardening recovery upon healing, will be described. This presentation includes the experimental work carried out to identify the damage and healing parameters of the model described in [1]. Modifications and extensions to that theory that were necessary to represent the experimental data will also be presented.
