Development and Characterization of a Self-Stressing Shape Memory Alloy (SMA)-Fiber Reinforced Polymers (FRP) Composite Patch for Repair of Cracked Steel Structures
… patch consists of nickel titanium niobium (NiTiNb) SMA wires embedded in a fiber reinforced polymer (FRP). The self-stressing patch can be bonded to the steel member in the vicinity of a crack. The prestressing force is generated by restraining the shape memory effect of the embedded NiTiNb …
