Strain Transfer From the Host Structure to Optical Fiber Sensor

Abstract:

Article Preview

Optical fiber sensors with light weight, small dimension and immunity to electromagnetic interference are considered as a superior structural health monitoring device. It is well known that the strain transfer from the host structure to the optical fiber sensor is dependent on the bonding characteristics such as adhesive layer, protective coating and host material. In this investigation, a theoretical model with three concentric cylinders represented optical fiber, protective coating, and host material, respectively, is proposed to determine the strain in the optical fiber sensor induced by the host structure. The theoretical predictions are validated with the numerical analysis using the finite element method. The effect of host material on the strain transferred is presented through a parametric study.
