【Abstract】 In order to study how the static preloading affects on the buckling stability of columns or cylindrical shells, a simple imperfection-sensitive elastic-plastic model is used. The axial and lateral inertia effects are considered in the model. The effects of load parameter factors on dynamic buckling are discussed with emphasis.更多还原
