| Abstract: | Stress analysis of the service spherical shell with the staggered joint defect has been accomplished with the use of the superparametric curved shell element with 8 nodes and 40 degrees of freedom which better simulates the arbitrarily curved shell.Meanwhile,finite element method which deals with the staggered joint defect has been stated in detail,and the stress concentration factor of the staggered joint defect was obtained. |
