Trying to apply a force to a hole

Trying to apply a force to a hole

Trying to apply a force to a hole

(OP)
Hi
I am new here and to algor. I trying to apply a force to a hole. I want to use like a bearing load. well that is what it is called in others software. I have tried to spilt the surface in the hole and applying the force, but I get a very high stress in the hole split. I think I have to use variable surface load, but I can not get the load right. And I have tried getting help from Algor, but nothing there after autodesk toke over. anyone can help?

Thanx

Upload an archive and let us see what you are doing.  It sounds as though you are using brick elements and attempting to load the inner surface much like a bolt contacting the hole.  If this is the case, you can select the lines (edges) of the elements defining the surface of the hole where you want to apply the load and just modify the surface number for the entire area ...no reason to "split the surface".  If you are trying to use some type of varying load (like the Hertzian contact yielding, but still the center of the load being greater than the edges) then we can probably help, but it will be easier for us to see the archive, modify it, and upload it back.

To create the archive, just open the model in FEMPRO.  Go to File: Archive: Create and select "without results" since you probably don't have any yet anyway.

Sorry about Algor's tech support...I was concerned about this when I found out Autodesk bought them and I heard about some of the reorganization.

Thanx GBor

I will do that. It is a brick element, imported from 3D CAD. Just part with two holes, one is suooprted and the other applyed a force tension. (from a shaft)

just modify the surface number for the entire area???? How do I do that?

Thanks GBor! This was a great help to me - I was having similar issues to the OP, and this has resolved it for me.
