| Abstract: |
| In this paper, the stress condition for convex cone-cylid ical jointed shell under uniform external pressure is analysed by finite element method with SAP5 program. The calculated results are in good agreement with the data obtained from steel model test. The present analysis reveals mechanical characteristics of such structure and proves the fact that the high stress cf near intersection of convex cone-cylindrical jointed shell can be efficiently reduced. A simple and effective strengthening method is also presented for structural design of submarines. |
