Preliminary Studies on Damage Tolerant Strategies for Composite Design and Health Monitoring

摘要

This report results from a contract tasking The University of Sheffield as follows: The proposed exploratory work will focus on the following 4 interconnected areas and related issues: The development of highly sensitive techniques for detecting and characterizing various types of damage in a composite material utilizing minimally invasive, non intrusive, permanently attached sensors and actuators, which is an open issue and should be first addressed. The question how reliable and effective is a given SHM system to detect and characterize damage-should be formally and qualitatively predicted. The question how serious is the effect of detected damage on the performance and integrity of the monitored structure-should be quantitatively answered. Finally, the issue of possible actions required for proper damage mitigation and remedy has to be addressed.
