A series of tests investigating dynamic pulse buckling of a cylindrica
l shell under axial impact is compared with several finite element sim
ulations of the event. The purpose of the study is to compare the perf
ormance of the various analysis codes and element types with respect t
o a problem which is applicable to radioactive material transport pack
ages, and ultimately to develop a benchmark problem to qualify finite
element analysis codes for the transport package design industry. Alth
ough the finite element codes used in this study utilize similar eleme
nt technology, there are differences in the numerical solutions. Furth
ermore, this study demonstrates that experiments-which are typically a
ccepted as the ''correct'' answer-can have multiple results because of
design sensitivities. Multiplicity of experimental results suggests t
hat experiments performed for numerical benchmarks should first be num
erically evaluated for such sensitivities.
