| Abstract: | The problem of the stresses in the edge of the hole on the spherical head is discussed by the non-mement theory and the mement theory in this paper. Used these theories, the stresses in the convex edge of the hole and the plate edge of the hole are seperatly analysed, and the defference between them is pointed out. The new design method and the new criteria are indroduced. |
