ABSTRACT

Stress Relaxation of Superelastic Shape memory (NiTi) Alloy under bending and torsion is uncommon in literature. Therefore, experimental set up has been devised and test results are obtained for superelastic SMA.Unlike the other common engineering materials superelastic SMA it gives dramatic reduction in stress. In this paper, therefore, results of stress relaxation of superelastic shape memory alloy under bending and torsion are presented graphically and interpreted in terms of stress induced martensitic transformation.
