| Abstract: | Based on Karman nonlinear equations, post buckling behavior of the clamped orthotropic shallow conical shell under uniformly distributed pressure is studied. By means of the modified iteration method, the approximate formulas of the second degree for load deflection and critical load are obtained, and using these formulas the numerical results as l 2 =0.6,1.4and 1.8 are calculated. |
| Keywords: | orthotropic shallow conical shell post buckling the modified iteration method. |
