摘要
介绍球形封头在外压下的失稳计算 ,应用小变形理论、能量分析法和大变形理论公式所计算的结果与实际结果相比较 。
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.
