The paper is devoted to a kind of egg-shaped shell with varying wall thickness subjected to uniform external pressure. The numerical buckling performances of several such shells are presented, which are compared with corresponding equivalent egg-shaped shells with uniform wall thickness. It is indicated that the buckling capacity of egg-shaped shells with varying wall thickness is greatly improved; furthermore, such shells are less sensitive to initial geometric imperfections than those with uniform wall thickness. To validate the proposed numerical approach, three nominally identical egg-shaped shells is tentatively fabricated, accurately measured, slowly tested, and numerically studied. A good agreement between experiments and computations are obtained.
