Hi ,

Im new to FEA and I’m trying to carry out a non linear FEA on a cardiovascular stent.

More specifically, I’m trying to increase the stents inner diameter to 3mm using a uniform increasing pressure on the stents inner surface.

From this I’m trying to determine the max pressure that causes the stent to reach an inner diameter of 3mm.

Unfortunately I’m not having much luck.

Any help or guidance on this matter would be really appreciated  

I’ve attached an image of the boundary conditions.

Thanks
