Effects of surface cracks and coating on fracture behaviour of microstructured silica optical fibers

Bai, Ruixiang & Yan, Cheng (2007) Effects of surface cracks and coating on fracture behaviour of microstructured silica optical fibers. In Fifth Australasian Congress on Applied Mechanics (ACAM 2007), 10–12 December, 2007, Brisbane, Australia.

Abstract

The fracture behavior of microstructured silica optical fibers containing surface cracks in tension was investigated using a simplified 3D analysis. Strengthening caused by the polymer coating was considered to be associated with the closure stresses uniformly applied to the crack surfaces, which were generally created by the thermal mismatch between the coating resin and the silica glass. The stress intensity factor of the surface cracks in tension was evaluated with considering the crack configurations and surface coating. The effects of crack configurations and closure stresses on the failure loads were also discussed.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
