Abstract :
Nonlinear contact arithmetic of ANSYS system is employed for simulating hole-edge stress of sheared bolt. The preload of sheared bolt is caused by cool method. In this paper, an evaluation formula of bolt joint stiffness is presented to obtain relative curves between bolt joint stiffness and thickness of lapped plates. Some reliable conclusions are shown for simplifying computation of lapped bolt from complex structure.
