| Abstract: | Based on an established stochastic weighted residual method formulation, stochastic buckling of a cylinderic shell is discussed. The net collocation point method with spline function is proposed to derive the formulation system of stochastic buckling analysis for cylinderic shells under various boundary conditions. The efficiency and validity of SWRM are verified by the computation results of some numerical examples. |
