Abstract(s)

This work presents an adapted numerical model using as basis Ansys Mechanical solver to simulate the behaviour of a shape memory alloy (SMA) circular beam. The analysis includes quasi-static and traction-compression cyclic cases. Since the Ansys Mechanical solves mainly the first case, the other result is obtained using the adapted algorithm based in a developed theory. The final results show the superelastic behaviour through stress-strain diagram for the material and displacement-time curve of a free vibration system.
