    Static study of a threaded connection in bending and tension

    Tony Hepp

      I'm attempting to conduct a static load study on an assembly comprised of five parts.  There are three different local contact types: no penetration, bonded, and shrink fit.  The shrink fit contact relates the male/pin threads of one part to the female/box threads of the mating part.  The thread is a 3.63" stub acme.  Please see the image provided.  The left end of the assembly is fixed, while a tensile and bending force is applied to the other end.  Having removed 7/8 of the assembly via a cut in the model, I've applied a symmetry restraint to the affected part surfaces. 

       

      My question:  Is the shrink fit contact type appropriate?
