Hello,

could you please tell me how can I model a bolted connection (with washers) of a bracket to some structure properly? I thought it would be good to put the first RBE2 element (DOF=0) on the hole surface (left in the picture below) and the second RBE2 on the washer surface. And then somehow connect them rigidly. But I realized I'm not sure what to do next. I read about CBUSH elements or something like that. Could you please give an explation?

    Hi Zdeny,

     

    Please watch this video. You will get an idea on how to create bolted connections.


     

    Thank you

    Thank you for your reply Premanand,

    but I can't see any washers in that vieo. In my case, I just have 1 fixed component for topology optimization. Will the results be right if I use just RBE2 + (independent node DOF=0)? Do I have to care about pre-tension in the bolt connection?
