Strain measurement and stress analysis in the vicinity of a Fiber Bragg grating sensor embedded in a composite material - ScienceDirect
The paper presents the results of a numerical analysis of the stresses in a polymer composite material (PCM) in the vicinity of an optical fiber embedded in the material, and the results from estimating the reliability of the strain values calculated on the basis of fiber-optic sensor data. A comparative analysis was carried out for the PCM represented as a homogeneous medium and as a laminated material for different directions of the prepreg reinforcements relative to the fiber and for different geometrical parameters of the resin pocket in the vicinity of the fiber....
