Hello,

 

I want to simulate a rivet Joint just applied shear force. Between the rivet and the hole in the metal Sheets is a gap.

I get convergence  but the rivet turns a Little. u can see it if u watch the displacement Contour plot on the rivet which is not symmetric. Is that because of the coarse mesh?

I tried to use gap elements but maybe i put some wrong Setting.

attachted are the model. Can anybody help me to fix the Problem?

Hi,

 

I think that is because of the force the rivet deformed in the same direction. To confirm can you output rotational displacements?

Sorry, I am not sure what u mean with "contrains rotation of rivet". :unsure:

The rivet is a solid how shall i put contrains rotation?

If I apply a constrain at a node of the rivet (DOF 2) that the rivet can just move x and z it doesnt help me, because later I want to apply also forces in other direction. Thats why i thought gap elements working, but somehow not with my current settings.

Any idea?

Hi,

 

Ok, I noticed that rivet is modelled with solids. I will check if there an approach for the same.

 

Right now what I am thinking is uisng stick contact  for rivets if you have slide contacts.
