Pipeline buckling detection by the distributed Brillouin sensor
We conducted strain characterization experiment to monitor steel pipe buckling for the first time using distributed Brillouin sensor system. One specimen was prepared by locally thinning the inner wall to initiate buckling. An axial load was applied to the specimen and increased while compressive strain was measured by both Brillouin sensor and the strain gauges. With the Brillouin sensors, we observed compression in the whole specimen while elongation was detected in the neighbourhood of the thinned wall at onset of the buckling for the first time. The buckling was identified and localized with the Brillouin sensor measurement.
