    Is it possible to add a bond above a shrink fit?

    Mark Dougall

      Hi,

       

      I have a couple cylindrical parts that in the real world will be shrink fitted to each other and then welded on top. I'm wondering if this can be represented accurately in simulation as when I attempt this large displacement occurs and I'm assuming its because the simulation doesn't take into account that the part is shrink fitted THEN welded so is trying to do both at once.

       

      Have attached the assembly with a bonded contact set suppressed. This suppressed contact is what I want to represent but obviously after the shrink fit has been applied. The displacement in the attached assembly currently stands with a max of 1mm which sounds right but if I unsuppress that contact set it jumps up to 8mm which sounds wrong.

       

      Also picture of what I would like with the circled feature representing a weld, the red line representing the bond to the part below and the orange line representing the shrink fit:
