Current Topic:
Press Fit Pressure
So, I have a design that has a tube press fit inside a head.  The head will have a twisting motion, torque applied to it.  I'm trying to find out the max torque that can be applied that will not allow the head to spin free of the tube.

I can find the following info:

- COF between the tube and the head (depends on mat'l used)
- Diameter of tube
- Diameter of hole in head
- Material Area that the head and tube have in contact

What I'm drawing a blank on is how do I model the pressure (force that spread out over the area of contact) acting on the tube (or head) due to the press fit.

Any ideas?
