Apply outward radial pressure of same magnitude on a inner 2D ring

Please login with a confirmed email address before reporting spam

I would like to investigate the relation between the pressure and the diameter of a 2D ring configuration. As shown in this picture, I would like to apply the radial pressure with the same magnitude to the inner surface of the 2D ring structure, but there seems to be only loading in x or y direction that can be applied to the structure. My question is that how to apply the radial pressure to the inner surface of a 2D ring structure?

I will very appreciate anyone could help that! Best wishes Ricky

There are several ways to do this.

Easiest: one of the options under Boundary Load is...pressure.

Next (if no large displacements): write it out in terms of components.

Another option: use surface normals.

Hi Dave Thanks for that information. Could you please give me a bit more information on theses methods?, as I still didn't quite get that. Best wishes Ricky
