| Abstract: | Through the FEM analysis of a spherical shell having a spherical,ellipsoidal or long ellipsoidal cavity in central wall under internal pressure,a series of curves of stress distributions and stress concentration factors were drawn,and the laws of stress distributions and stress concentration factors which a cavity flaw influence a spherical shell were concluded. |

| Keywords: | spherical shell cavity stress distribution stress concentration factor |
