A STUDY OF BUCKLING AND SNAPPING UNDER DYNAMIC LOAD

Abstract

The behavior of a shallow arch and a thin ring under a dynamic pulse loading is studied for a wide range of geometric and load parameters. The nonlinear dynamic response and static load deflection characteristics of the systems are related and employed to define dynamic elastic snapping and dynamic elastic buckling. When such a relationship cannot be established, the mechanism of dynamic elastic-plastic buckling is introduced. Critical dynamic load criteria are specified, and critical dynamic load data are developed as a function of structural geometry and load duration. Finally, a classification scheme for dynamic load problems is suggested.
