Probability of static fatigue failure in optical fibers

Abstract

An expression for the probability of static fatigue failure in glass is developed based upon a Weibull‐type cumulative strength distribution and a fracture mechanics slow crack growth law. The validity of the analytical model is tested with tensile strength and static fatigue data for fused silica optical fibers. Good agreement between the model and experimental results is demonstrated. Examples for using this model as a predictive tool are presented
