| Abstract: | The nonlinear thermal buclding of symmetrically laminated cylindrically orthotmpic shallow spherical shell under temperature field and uniform pressure including transverse shear is studied by using the modified iteration method. And the analytic formulas for determining the critical budding loads under different temperature fields were obtained. The effect of transverse shear deformtion and different temperature fields on critical buckling loads were discussed in a numerical example. |

| Keywords: | modified iteration method temperature field buckling laminated shallow spherical shell |
