摘要: The large diameter threaded connections are components with high importance in the heavy mechanical systems. At elements subjected to variable loads one of main causes failure is represented by fatigue. This phenomenon accentuated occurrence local stresses on thread root. In this context, correct evaluation and their correlation fatigue behaviour has a major assessment remaining life connections.The paper focused finite element analysis bolts two types threads profiles: trapezoidal square. For simulations were performed using four nominal different loading setups. summited static order determine distribution area. maximum values Von Mises obtained exported studies. differences between results for outlined.
