Crack development monitoring using distributed fiber optic sensing technology

Cracking in clay is an important phenomenon that affects the long-term durability of many civil structures such as dams, levees, embankments, and landfills. In order to understand the behavior of cracking in clay, researchers at SRG…conducted a four-point bending experiment on compacted kaolin clay beams. Distributed fiber optic sensors (DFOS) were embedded in the clay specimens at different heights and used for strain monitoring during crack development during beam bending.
