Abstract : 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.
