SMA Bending Sheet

In this example, the shape memory properties of NiTi alloys is present. In this case, we have an SMA sheet. A rigid mold deforms the sheet causing the crystalline structure of the material to change from twinned martensite to detwinned martensite. This way, the sheet is ready for the shape memory effect. When the mold is removed, the material is temporarily deformed. When applying a thermal condition of +85ºC to +120ºC, the small SMA plate recovers the initial flat shape, without permanent deformations, thus completing the cycle. In this state, the crystal structure of the Nickel-Titanium alloy adopts the austenitic state, until it cools down and returns to the twinned martensitic state.

It is a clear demonstration example of the shape memory effect, in this case, applied to a sheet. The deformed element adopts a curved shape but this can be any other. Everything depends on the shape of the mold, being able to adopt any (letters, drawings, etc.)

This simulation runs through three steps:

  • 1st step: The sheet deforms by the upper part of the mold.
  • 2nd step: Mold is vertically removed.
  • 3rd step: Heat makes the sheet to recover its initial flat shape.

Characteristics of the model:

  • Nickel-Titanium alloy
  • Transformation temp. Af=+90ºC
  • Sheet dimensions: 120x10x1 mm
  • Thermal condition: 85ºC-120ºC
