| Abstract: | A small dimensional sensor with two holders in both sides of fiber Bragg grating(FBG),which is protected and packaged by a stainless steel tube,is used for strain measurement.Experiments were conducted on the universal material testing machine to calibrate the strain transferring characteristics in different parent materials.The strain measured by FBG sensor agrees well with the theoretical result.The tube-packaged strain FBG sensors are applied to the vibration experiments of artificial concrete dam models... |
