A review on shape memory alloy structures

Abstract

This paper presents a literature review on smart material NiTi shape memory alloys and their structural applications. Shape memory alloys are capable of recovering large strains as a result of martensitic transformation. The NiTi shape memory alloy is widely used because of its large memory strain, superelastic behaviour and greater thermal stability. The review includes the behaviours and the characteristics of the NiTi shape memory alloys, and also covers, in brief, structural applications and limitations.
