Stent analysis

[yomi213]

Hi,

I am working on stent analysis.
The stress values are much higher than tensile strength.
The document below has stent design with analysis.
Could you please suggest me?

Thanks in advance.

Have you included elastic-plastic material properties?

Also, you might want to reconsider using a pressure boundary condition to expand your stent. I think that the best way to capture that behavior is probably to expand a cylindrical shell inside of the stent.

Hi,
I have included the material properties as elastic-plastic material.
Probably I will try expanding a cylindrical shell inside the stent.

Thank you for your advice.
