| Abstract: | The phenomena of the stress concentration at the rims of the step holes in a spherical vessel have been carefully analyzed in this paper. By simplifying the mechanical model in theory of elasticity,the theoreti- cal formulas of expressing the concentrated stress are successfully obtai- ned. The conclusion of this paper provides a scientific basis for the safety credibility of designing a spherical vessel with step holes. |
