    Modelling point contacts.

    Jason Richardson

      I am trying to simulate a single chain link which has a tensile load applied to it by identical chain links.

       

      I've set up a 3 chain assembly for it, and applied a fixing restraint to the one end-link and a 1000kN force on the opposing end-link.

       

      The problem I'm having is with the point contact between the links. I'm aware that it causes infinite stress and an area of contact should be required as would be found through indents in used chain.

       

      I've been given the task of finding the required material for this chain to yield at no lower than 1000kN, and would appreciate someone with experience sharing with me their method to approaching the problem.

       

      Attached the assembly if you fancy helping me out.
