SMA spring:
- 2 coils
- D1=0,75mm
- D2=5,6mm
- Nickel-Titanium alloy
- Transformation temperature Af=23ºC
- Force applied = 5N
- Thermal condition applied = 80ºC
This is a simulation under Ansys Workbench 15. Two steps:
1st step: 5N load is applied to one end while the other remains as a fixed support. The spring gets deformed in cold state
2nd step: a thermal condition of 80ºC (over Af) is applied. The spring recovers its original shape without unloading.
