| Abstract: | Based on Reissner's Hypothesis and variational principle, the equations of large deflection for a shallow spherical sandwich shell are derived. Analytic solution of the critical buckling pressure for the shells with two types of boundary conditions is obtained by use of modified iteration method. The effects of geometrical and physical parameters on the buckling behavior is also discussed. |
