Publikováno v: Sensors, Vol 21, Iss 16, p 5423 (2021)

Despite recent publications, the strain transfer in distributed optical fiber sensors is still often overlooked and poorly understood. In the first part of this paper, strain transfer is shown to be driven by a second-order differential equation, whe

Concrete Crack Monitoring Using a Novel Strain Transfer Model for Distributed Fiber Optics Sensors

Autor: Antoine Bassil, Xavier Chapeleau, Dominique Leduc, Odile Abraham

Publikováno v: Sensors, Vol 20, Iss 8, p 2220 (2020)

In this paper, we study the strain transfer mechanism between a host material and an optical fiber. A new analytical model handling imperfect bonding between layers is proposed. A general expression of the crack-induced strain transfer from fractured
