| Abstract: | Fiber Bragg grating(FBG) strain sensor packaged by the carbon fiber reinforced polymer(CFRP) is developed which can be used to measure strain in the concrete.And the relationship between the distribution of axial strain and structure parameters is analyzed.The static index is obtained through the calibration testing on the uniform strength beam,and the dynamic response of FBG is researched by shock test in split Hopkinson pressure bar(SHPB).The results indicate that the linearity of FBG strain s... |
