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?
