Distributed Strain Measurement along a Concrete Beam via Stimulated Brillouin Scattering in Optical Fibers
Figure 5
(a) Measured strain distribution along the length of the beam with fiber bonded with polyurethane (position D); (b) measured strain distribution along the length of the beam with fiber bonded with polyurethane (position C). Solid line = loading step. Dashed line = unloading step. Blue line = 50 daN. Red line = 100 daN. Magenta line = 150 daN. Black line = 0 daN.
