Experimental study on the influences of static strain aging, apparent size effect and heating input level on stress recovery behavior of Fe-SMA bars
In this study, six groups of Fe-SMA bars with nominal diameters of 10, 14, and 30 mm were first designed, and then heating activation tests (with activation temperatures of 100–350 °C) were conducted after strain aging times ranging from 0 to 48 h, simulating typical construction timelines. Test results demonstrate tha...
