| Abstract: | The calculation of spherical heads losing stability under external pressure was discussed in this paper.The reality results was compared with the calculating ones which were obtained by using small deformation theory,energy analytic method and big deformation theory.Then how to define the standard of the secure coefficient was studied on. |
| Keywords: | external pressure lose stability deformation theory calculation |
