• 論文の詳細を見る

• This paper discusses on a distribution of the contact stresses when a circular flange is fastened with tap bolts to a base which is large enough comparing with the circular flange. In an analysis, by replacing the circular flange and the base with two finite cylinders. the distribution of the contact stresses is analyzed as a two body contact problem by three dimensional theory of elasticity. In order to know the distribution of the contact stresses near a bolt hole, the contact proble between two hollow cylinders is analyzed using three dimensional theory of elasticity. In addition, the force ratio, which is the ratio of an increment of a bolt axial force to an applied load, is analyzed. More-over, by taking a bending moment caused in bolts into consideration. the maximum stress is analyzed. For verification experiments are carried out and analytical results are in a fairly good agreement with experimental ones.
