Abstract
Shape Memory Alloy (SMA) is able to recover big strains beyond an appropriate heating and/or mechanical loading procedure. Numerous uses being exploiting such notable characteristic and the NiTi wires are of particular attention to conduct the connections in various industrial states. The present research aims to achieve a numerical simulation of the superelastic conduct of the NiTi shape memory alloy wire, using Finite Element Method by employing commercial ANSYS 15.0 software. The influence of the material responses parameter (Alpha) on the stress–strain behavior during loading and unloading of superplastic shape memory NiTi wire has been investigated. Axisymmetric wire element is employed, and characteristic responses are analyzed by considering von Mises stress and von Mises strain curves at constant time for various values of Alpha parameter from during the bending process. The numerical simulations manifested the features of superelastic recovery, which is also in terms of time.
