In designing bolted joints, it is important to examine the tightening effect and to estimate the force ratio, that is the ratio of an increment of bolt axial force to a load. Up to now, in order to improve the tightening effect, raised faces of interface have been used. But the use of these interfaces depends on experience and the theoretical grounds are not made clear. In this paper, in the case of circular flanges having raised faces the tightening effect is analyzed using a three-dimensional theory of elasticity and point matching method. Then the force ratio is analyzed. moreover, with an application of the load a bending moment is produced in bolts and a stress is caused by the bending moment. The bending moment is also analyzed. For verification experiments are carried out. Analytical results are in a fairly good agreement with experimental ones.
