Distributed Strain Measurement along a Concrete Beam via Stimulated Brillouin Scattering in Optical Fibers
Figure 4
(a) Measured strain distribution along the length of the beam with fiber bonded with epoxy resin (position B); (b) measured strain distribution along the length of the beam with fiber bonded with epoxy resin (position A). Solid line = loading step. Dashed line = unloading step. Blue line = 50 daN. Red line = 100 daN. Magenta line = 150 daN. Black line = 0 daN.
