Thermo-Mechanical Behavior of the Shape Memory Alloy Strip

Abstract:

As a new type of smart material, shape memory alloy (SMA) is widely used in the aerospace, biomedicine, civil engineering and so on due to its unique mechanical and physical properties such like the shape memory effect, pseudoelasticity and good biological compatibility. This paper investigates the numerical simulation and application of the SMA component: A SMA strip, which has been pre-curved in the room temperature and is expected to extend upon heating and shorten on cooling along the curve. According to the investigation of the thermal respond of the SMA strip component, it can be seen that the temperature of the phase transformation can increase with the initial transformation strains and the process of the phase transformation in the boundary is more complex due to the complicated stress state.
