Abstract
This paper deals with the distribution of contact stress and the force ratio (the ratio of an increment of bolt axial force to an external load) of bolted joints fastened with tap bolts, when a clamped part with raised face metallic gasket is the cover of a pressure vessel. The distribution of contact stress is analyzed as a three-body contact problem, using the three-dimensional theory of elasticity. The effects of the stiffness and the position of gaskets are shown on the distribution of contact stress in numerical computations. The contact stress is measured by means of ultrasonic-waves. Next the force ratio and the maximum stress caused in bolts are analyzed. For verification, experiments are performed. The analytical results are in fairly good agreement with the experimental ones. In addition, concerning the effective gasket yielding width and the moment arm standardized in JIS, the analytical results are compared with the values obtained from JIS.
