Inflation of angioplasty balloon
Inflation of angioplasty balloon
(OP)
Hi I'm trying to model the inflation of a simple model of an angioplasty balloon consisting of a straight cylinder with tapered ends to about 4 times the original diameter of the cylinder however I cannot get many of my models to converge and for any that do converge the resulting increase in diameter is minimal. At present I am more concerned with achieving the required deformation for the given geometry than with using accurate material properties. I am currently using Standard but would Explicit be more appropriate? I am inflating the balloon using a pressure load and have constrained all displacements at its ends. Any input you may have would be appreciated. The input file is attached.

2. How accurate is a fixed constraint at the top and bottom? That is as if it were glued to 2 steel plates. (I think this is the main issue)
3. Can this be an axi-symmetric model?
I hope this helps.
