Abstract
Abstract A series of tests investigating dynamic pulse buckling of a cylindrical shell under axial impact is compared with several finite element simulations of the event. The purpose of the study is to compare the performance of the various analysis codes and element types with respect to a problem which is applicable to radioactive material transport packages, and ultimately to develop a benchmark problem to qualify finite element analysis codes for the transport package design industry. Although the finite element codes used in this study utilize similar element technology, there are differences in the numerical solutions. Furthermore, this study demonstrates that experiments—which are typically accepted as the “correct” answer—can have multiple results because of design sensitivities. Multiplicity of experimental results suggests that experiments performed for numerical benchmarks should first be numerically evaluated for such sensitivities.
