A laboratory testing and engineering modeling study was completed to determine the influence of fiber optic coating damage caused by microbend contact on the performance of microbend sensors developed based on relatively low cost single-sided microbending technique using a multimode optical fiber. A testing method was designed, developed and implemented to determine the loads that caused optical fiber glass-coating debonding and coating fracture. Finite Element models of the fiber-deformer system were developed to study the failure modes and predict the stresses that caused this failure. Loads and displacements predicted by Finite Element models were found to be in good agreement …
