| Abstract: | In this paper, fundamental equations of nonlinear stability of thin spherical cap with orthotropic laminates under the action of uniformly distributed load are derived. The equations can be solved by the aid of the modified iteration method. Analytical expressions of solution are given. The curves of load-central deflections are depicted. The results are excellent and can be referenced by engineers. |
