    how to simulate a non-preloaded bolt connector?

    Paul Fichman

      The software simulates a bolt connector by rigidly connecting the bolt head to the plate, thus, if we consider 2 plates attached with a non-preloaded bolt:

      pulling the plates sideways will shear the bolt.

       

      but when running the simulation I found a bending moment on the bolt. I expected to find only shear force.

       

      is there a workaround to the problem? I have a complex model using bolts and using solid bolts with contacts will make the simulation run forever...

      I am only intrested in finding the reaction on each bolt.

       

      by the way, if I preload the bolt enough for the friction between the plates to eqwal the external force, the results make sense.
