Load and Damage Monitoring of Intelligent Structures Based on Optical Fibers

Abstract

In this paper we study on a novel method to distinguish the loading location on structures based on optical fiber network. The principle of detection and monitoring system is illustrated in the paper and the experiments of loading position judgment are conducted. The experimental data and curves meet preferably to the analysis of theory. The results obtained are encouraging offering the possibilities of employing this novel method of loading position judgment in intelligent composite structures. The system of monitoring and analysis is approved to be real-time, effective and reliable and the research in this paper offers a new way of application of the special optical intelligent structure.
