Non-symmetrical large deformation of a shallow thin conical shell

In this peper, non-symmetrical large deformation problem of a shallow conical shell is studied by two-parameter perturbation method. The third-order approximate analytical solution of the deformation of a shallow conical shell subjected to linear loads is abtained and the characteristic curves of load-deflection on a perturbin point are portrayed. The similar questions of other kind of shell and-plate can be disscussed by using this paper's method. As the examples, the large deflection of plate and shallow conical shells with different initial deflections is discussed.
