The strength and failure of silica optical fibers
Yan, Cheng, Bai, Ruixiang, Yu, Hong, Canning, John, & Law, S.S. (2010) The strength and failure of silica optical fibers. Physica Scripta, 2010(T139), pp. 1-5.
The mechanical strength and failure behavior of conventional and microstructured silica optical fibers was investigated using a tensile test and fracture mechanics and numerical analyses. The effect of polymer coating on failure behavior was also studied. The results indicate that all these fibers fail in a brittle manner and failure normally starts from fiber surfaces. The failure loads observed in coated fibers are higher than those in bare fibers. The introduction of air holes reduces fiber strength and their geometrical arrangements have a remarkable effect on stress distribution in the longitudinal direction. These results are potentially useful for the design, fabrication and evaluation of optical fibers for a wide range of applications.
