While I've done some Simulation studies in the past, they've always been straight forward studies. This time I need some help with the set up.
I have an 8" diameter rod threaded into a 1/2 tube with a 3" wall thickness. They are Acme threads at 1/2" pitch. Once threaded together, the rod will be welded to the tube as well. The question is whether the threads, and weld, will withstand 24,000 lbf. (FOS of 4). I did create the threads on the two pieces as I'm guessing that I'll need to create contacts between them, but I'm hoping that someone can tell me the best way to go about this.
