| 摘 要： | Nonlinear strain is used to formulate the energy functional of combined structure withseveral kind of shells.The nonlinear finite element method (N.F.E.M.) is proposed forcalculating bending and buckling of the structure subjected to external hydrostaticpressure.The numerical results are found to be in good agreement with experimental ones.
