| Abstract: | The nonlinear axisymmetrical buckling problem of symmetrically laminated cylindricallyorthotropic shallow spherical shells with a cincular hole at the center under uniform pressure including transverse shear is solved by using the modified iteration method, and the analytic for-mulas for determining the critical buckling loads are obtained finally, the effects of transverseshear deformation and size of the hole on the critical buckling loads are discussed in a numeri-cal example. |
