Abstract : Numerical and experimental studies are carried out to characterize the response time and shape memory effects of an R-Phase NiTi alloy. The results of the numerical analysis indicate that the response speed of the R-Phase alloy can be four to six times faster than martensite NiTi alloys. The experimental results demonstrate that the R-Phase NiTi alloy is a superior smart material to the martensite-based NiTi alloy when response time is indeed a requirement. (AN)
