Multiple candidates for replacing mild steel in automotive structures have been proposed, such as advanced high strength steels (AHSS) aluminum or magnesium alloys, and composite materials [1-3].
AHSS, in particular, are attractive candidate materials, offering higher strength and the opportunity to reduce weight through use of thinner gauges.

Introduction SMA is a kind of unique smart material which has shape memory effect, superelasticity, high damping, strain is sensitive to resistance, etc, has attracted considerable attention and becomes a research hotspot.
Recently, with the development of smart materials and structures, as well as the improvement of materials processing technology, SMAs were embedded in concrete members or structures instead of ordinary steel reinforcements.
Then the constitutive model was established, which was based on superelastic SMA material properties.
The stranded SMA materials used in this study were similar to those of conventional SMA steel.
