Application of Continuum Damage Healing Mechanics to Self-Healing Composites

Contimuum Damage Healig Mechanics is an extension of CDM recently developed by the authors to model healing process in a variety of materials including rock salt, sinterized metals, ceramics, and polymer-matrix composties, bone and so. on. While the theoretical framework, of CDHM is general, parameter identification depends on the particular material being modeled and the specific material tests that are feasible to conduct for that class of materials. This presentation deals with the application of CDHM to the specific field of fiber-reinforced polymer-matrix composites. An overview of CDHM will be presented followed by a description of parameter identification. Results are shown in order in validate the numerical model of healing behavior of damaged polymeric matrix composite. Healed and not healed cases discussed in order show the model capability and to describe possible evoltution of the healed system.Copyright © 2003 by ASME
