Accuracy Improvement of Residual Stress Measurements in the Tube by FBG Using the Genetic Algorithm

The genetic algorithm (GA) method is used to demodulate the strain distribution of fiber Bragg grating (FBG), which improves the residual stress measurement accuracy of the tube in the hole-drilling method. The accuracy of the method is verified by simulation and experiment. Compared with the tradit...
