To emphasize the unique properties of Nitinol as compared to other materials, this study was conducted to differentiate the behaviors of two types of stents which are made of Nititol and 316L stainless steel during implantation.
Finite Element Modeling In order to emphasize the unique properties of Nitinol as compared to other materials, the implant process of two stent was simulated.

The FEM software PLAXIS was used to carry out two-dimensional simulations.The 15-node flat triangular element was chosen to mesh the culvert, fill, slope etc., In the surface between the materials, the contact elements were used.
(b). the idealized elastoplastic model were used to describe soil and embankment fill,the compressive strength of such materials was far greater than the tensile strength, and Mohr-Coulomb model was employed: (2) Where is the shear strength, the normal stress, the cohesion of the material, angle of internal friction of the material.

In addition, the main object of the torsion testing machine existing is metallic materials.
However, those for non-metallic, biomedical materials are unusual.
It can be analyzed to be a statically indeterminate structure through the mechanics of materials.
