.Stress-transfer characteristics of embedded fiber Bragg grating sensors[J].Optoelectronics Letters,2005,1(3):168-171 Stress-transfer characteristics of embedded fiber Bragg grating sensors BAO Ji-long CHEN Ying ZHAO Hong-xia College of Electronic and Information Engineering, Ningbo University of Technology, Ningbo 315016, China Abstract:       The shear lag theory is used to analyze the stress transfer from concrete matrix to FBG sensors based on that the FBG sensor and the concrete matrix are composite. The stress transfer formula and the coefficient are obtained. The experiments prove that the theoretical results of the stress transfer by the stress transfer formula are in well agreement with the experimental data.
