Summary

The shape memory alloy (SMA) is used widely in structural engineerings. It can change its form about 8% by small force. But it is recovered to the original memorized shape when the temperature is raised to the phase transformation point. By making use of this peculiar nature, many types of thermo-mechanical tools were developed. But the numerical analysis method for the SMA has not been established because of its complicated behaviour. It concerns with large deformation problems, thermo-anisotropy problems and constrained volume problems. It may also concern with contact problems.

In this paper, we propose the method to treat the SMA solid. As a practical example, a numerical analysis for the SMA coupler used in the Compact Troid Reactor is shown.
