Experimental Investigation and Stress Analysis on Static Fatigue Property of Optical Fiber

Abstract

This paper mainly presents experimental investigation and stress analysis on static fatigue property of optical fiber. By analyzing the weibull distribution of experiment, the weibull modulus was obtained. From the weibull distribution, the modulus decreased continuously with the decrease of stress, and a conclusion that experiment distributes discretely can also be drawn. Simultaneously, based on the experiment, we also obtain the feature life of optical fiber in different stress and s-t curve of the static fatigue experiment, as well as the analytical expression of static fatigue .
