Hi, all. I’m modeling a flanged connection under external tension with bolt pretension presented in [Birger IA, Iosilevich GB (1990) Threaded and flanged connections. Engineering, Moscow, 368p]. The dependencies of the additional load on the external load are obtained as a result, but they do not correspond to experimental data from book. Any idea what can I do wrong?
