• The design method of bolted joints with gaskets is generally based on experience, and the sealing performance is not made clear by theoretical analyses. In the present paper, discussion is made on the distribution of contact stresses in the bolted joints fastened with tap bolts when a clamped part with a gasket is the cover of a pressure vessel and is a circular flange. The distribution of contact stresses is analyzed as a three-body contact problem, using the three dimensional theory of elasticity. Moreover, the contact stress is measured by means of ultrasonic waves. In addition, the force ratio (the ratio of an increment of the bolt axial force to an external load) and the maximum stress caused in bolts are analyzed in taking account of the bending moment. For verification, experiments are carried out, and the analytical results are found in fairly good agreement with the experimental ones.
