Dynamic Buckling of Axisymmetric Spherical Caps with Initial Imperfections,

Abstract

Dynamic buckling loads are obtained for axisymmetric spherical caps with initial imperfections. Two types of loading are considered, namely, step loading of infinite duration and right triangular pulse. Results show that initial imperfections do indeed have the effect of reducing the buckling capacity for both dynamic and static responses. Solutions also indicate that pulse duration has a very significant impact on the magnitude of the dynamic buckling load, and that the step loading of infinite duration is the limiting case of a triangular pulse and provides the most severe loading situation for dynamic analysis.
