Abstract
Structural fatigue life prediction, especially for the structures in service, is still a world-wide big problem, which is the safety evaluation focus of structural health monitoring system. Generally speaking, by now we have no choice but to rely on the strain-time course to give statistical prediction of structural fatigue life. In this paper, a new kind of structural fatigue life prediction smart sensor, named smart fatigue life gauge, is developed. And its effect of resistance accumulation and statistical expression are studied. Then, the solution of fatigue damage life prediction based on smart fatigue life gauge is given. Results show that the smart fatigue life gauge is prominent in the field of structural health monitoring system.
