Radial Displacements

[mplishka]

Hi!

I have a ring that has varying wall thickness (It's almost symmetrical). I don't know the pressure on the inside surface, but I know the displacement. There is a displacement radially of .02 inches. How can I put this displacement in Z88? If there were a cylindrical coordinate system this would be easy, but unfortunately I don't see that.

Any thoughts?

Thanks!!

Mike

Hello mplishka,

try to use tori-elements (see theoryguide.pdf) to model your problem.

Working in cylindrical coordinate systems is not so common. Maybe we consider this application in further versions.

With kind regards.

Thanks, will look into it!

FRudolph,
It seems that the Tori elements are only for 2d analyses? The thickness of this ring varies in the z direction as well. So the thickness at a given x,y,z(1) thickness is T1 and at x,y,z(2) thickness is T2.

I need to see if I can simplify this in any other way.

Thanks!

Hello Mike,

you are always welcome.

If you have a specific problem you can also send the project file to our support-mail. Then we can take a look on it.

Thanks for using Z88 and have a great weekend.
