Test the fatigue strength of rivet with open round head

Generally, the structural life that requires fatigue checking is more than 10,000 times. However, the joint tests of more than 10,000 times show that most of the fatigue is destroyed at the hair section of the front area of the round head rivet hole.It is more reasonable to use the wool section to calculate the stress in the design if the hole percentage has no effect on the fatigue strength and the design is convenient.
