Superelastic NiTi Honeycomb

This model shows the properties of these smart alloys. For example, here a solid box causes deformation of the honeycomb along the weak plane of the element. Then the solid box moves back and the honeycomb recovers its initial shape. This is due to the superelastic behavior of the NiTi alloys. This way, it demonstrates that a 3D honeycomb structure may change to a 2D shape without permanent deformation in the material.

The example is a five hexagonal shape cells model. The lower face of the bottom cells attaches to the ground base plane while the rest remain free. In this simulation, you can see how the middle cell is the one which suffers bigger deformation, almost fully compressed. Even so, once the pressure releases, it recovers the original shape completely.

This could be considered as a dumping system. In fact, this is one of the main features of the superelastic alloys: energy disipation. It could be an inspiration for designing a dumping system. Stress levels can be observed on each point of the model. This way, you can improve and optimize it.

This is a two steps simulation:

Step 1: When a solid box moves vertically, the honeycomb deforms.

Step 2: The solid box moves away and the honeycomb recovers the original shape without permanet deformations, thanks to the superelastic property.
