Dynamic Buckling of Simply Supported Columns under Axial Slamming

Dynamic buckling properties of simply supported columns under axial fluid-solid slamming are experimentally investigated in this study. By observing the elastic-plastic responses of columns, the dynamic buckling criterion and the dynamic plasticity criterion of columns are defined and the relevant critical impulses are determined. The effect of the slenderness ratio of the column on the elastic-plastic dynamic buckling properties is also examined. The dynamic buckling characteristics of fluid-solid slammed columns are compared and discussed with respect to those of columns under solid-solid impact. It is found that they are different from those of columns subjected to either impulsive impact or impact owing to suddenly applied load.
