| Abstract: | In this paper several geometrical relations of angular deformation and the analytical expressions of local stresses in spherical vessels are established by analytical method. A concise and practical formula for calculating the stress concentration coefficient is derived, which shows that the stress concentration is related to angular deformation and increases with an increases of the square root of the ratio of radius to thichness. |
