| Abstract: | The stress distribution in ellipsoidal shells subjected to internal pressure is deseribad,it is pointed out that the stress state of a point in elllpsoidal shell is decided by A, the ratio of the length of the non-revolving axis to that of the revolving axis, and the position of the point in the shell. And the ocurring and expanding of the plastic deformation in ellipsoidal shells subjected to internal pressure are further analyzed. |
