Abstract
The buckling and vibration behaviour of curved panels subjected to various in-plane tensile edge loadings are studied using the finite element method. The first order shear deformation theory is used to model the doubly curved panels, considering the effects of transverse shear deformation and rotary inertia. The theory used is extended from the dynamic, shear deformable theory based on the Sander's first approximation for doubly curved shells, which can be reduced to Love's and Donnell's theories by means of tracers. The in-plane non-uniform internal stresses are obtained as the plane elasticity solution with reasonable accuracy, based on which the buckling and vibration results are obtained. The effects of different edge loadings, aspect ratio, thickness ratio, shallowness parameters are considered in the buckling and vibration analysis.
