Why is it important?
Shape-memory alloy wires excellent candidates for kernel elements in innovative strain transducers with dynamic ranges 4 to 5 times larger than the currently available strain transducers.
Perspectives
One of the current difficulties of SHM is the characterization of the macroscopic deformation response of structures to extreme events like strong ground motions, collisions and blast explosions. Presently, there is a gap between the analytical capabilities for predicting the nonlinear response of structures and associated damage parameters and the actual available information on the seismic response of structures. The research being performed aims at filling that gap, making use of shape-memory alloy (SMA) based technologies.
