I am trying to make a simulation for pushing a ball through a hole.

An example being a 2.5 inch diameter ball being pushed through a 2.440 inch hole.

Now the force behind it is a pressure pushing it forward.

I got some results but I know they are not correct.

The goal of this model is to change the pressure and material properties to strike a balance.

I did a non linear model and all the deformation and stresses were on the wrong side and the buckling just did a little corner on the lip.

I have Solidworks 2012 Premium.

Any help in setting the up would be appreciated (or a sample model to modify my design).

use a qtr symmetry model and split the ball so you only apply pressure the side that sees the pressure.
