Abstract:The R & D status of our structural health-monitoring group (SHMG) in 1999 is summarized. Activities of the SHMG are conducted as a university-industry collaboration program at the University of Tokyo, along with ten research organizations. Research themes include (1) the development of high-performance sensor system technology with newly developed sensors, (2) the development of a damage detection and self-diagnosis system for structural integrity based on micromechanical damage identification, and (3) the development of application technology for model structures. The sensor technology includes (1) the development of a small-diameter optical fiber sensor, (2) damage suppression in composite laminate systems with embedded shape-memory alloy films, and (3) the development of maximum strain memory sensors with electrically conductive composite systems. The sensor output is correlated with the underlying damage evolution in structures such as aircraft, satellites, high-speed trains, and large-scale civil infrastructures.
