Superelastic Letters

In this example, a set of letters form the word “Superelasticity”. The lower part of all the letters is fixed to the base plane while the rest of them remain free. 15 MPa applies to one of the faces of the model. This causes the deformation of the letters. In other words, the crystalline structure of the alloy changes from austenite to detwinned martensite. This is the characteristic of the superelastic property.

Finally, when the pressure ends, the letters recover the original form. In other words, the transformation cycle goes from the martensite detwinned to the initial austenite. As a matter of fact, this can be repeated thousands of times without the material showing signs of fatigue or permanent deformation. In the simulation, the points where the tension of the material is greater and the points where it is minimum can be appreciated. This data can be useful to redesign the piece based on these results and thus optimize the use of the material.

Get now this solved superelastic simulation file to start working on your own SMA projects.

This is a two steps analysis:

  • 1st step: Initially, 15MPa pressure applies on one side. Bottom is a fixed support.
  • 2nd step: Finally, release pressure. Letters recover its shape after pressure ends. No permanent deformation signs due to the properties of the alloy (Superelasticity).
