Variation of Dynamic Behavior of Shape Memory Alloy Bars in Tension under Cyclic Loadings

초록

It is known that the behavior of shape memory alloys depends on the variation of temperature and dynamic loading speed. However, the relationship between SMA behavior and cyclic loads is not clearly assessed. The relationship is very important in the field of seismic application of SMAs. Therefore, this study conducted several dynamic tensile tests of martensitic and austenitic SMA bars
