Abstract: In this article, the effect of interference fit on fatigue life of holed plate of mechanical joints was investigated both experimentally and numerically. In the experimental part, fatigue tests were carried out on the holed specimens in which oversized steel pins were force fitted to them. These fatigue tests were conducted on open hole specimen and specimens with 1, 1.5, 2 and 4 percent nominal interference fits at different cyclic longitudinal loads. From these tests the stress-life (S-N) data for different interference fit levels were obtained. The results show that interference fit increases fatigue life compared to open hole specimens. In the numerical part of the investigation, 3-D finite element simulations have been performed to obtain stress (or strain) histories and distributions around the hole due to interference fit and subsequent cyclic longitudinal loading using FEM package. The stress history from finite element (FE) simulation was used to explain t!
he reason for fatigue life improvement in the interference fitted specimens.
Keywords: Interference fit, fatigue, mechanical joint, finite element.
