question about kinematic coupling

[tatika]

Hi , i have a problem with a simple connection, and when i am applying a moment on a surface on this connection, this plate is not moving as i am expecting, it just moves in one direction and all the places of the plate to the same direction, i guess it has some relationship with the kinematic couplin, i have change the constrains but it is not working, can someone help me with this?

i am attaching the file, thanks a lot if someone can helps me

Could you explain your problem a little more. I think that the 2 plates in the back are fixed and you are providing a moment about the X-Axis on the front 2 plates. I did just look at the results and the deformation scale factor defaults to 7e6. Change that back to 1 for the actual deformations by going to Options>Common>Deformation Scale Factor>Uniform>1 I hope this helps.

Hi Rob, well my little connections is about two plates, i looks like 4 because i did a partition to each of the plates, the back plate is encastre and on the front one a moment is applied at x axis, this shoul be working in the next way: the upper part from the plate two showl be moving far from the second plate and at the lower part it should be having contact both plates and obviously the bolt should have deformation.

I would apreciate if you can help me with this it would be great. my problem is the way how this is moving and having deformations, i think it is because of the kinematic coupling, but if you know any other reason it would be fantastic. Thanks a lot

Try turning on Nlgeom and probably Automatic stabalization. Both are located in the edit step definition. I hope this helps.
