Theobject of this study is to determine the short-term burstpressure of metal cylinders under short-term dynamic loading conditions. Thefinite element method via the use of the LS-DYNA code(1998, LS-DYNA Theoretical Manual, Livermore Software Technology Corporation) is usedto carry out the study. The influence of the geometricparameters diameter (D) and wall thickness (T) as well asloading parameters such as the dynamic pressure versus time functionis examined. Additionally, an empirical formula based on experimental dataand incorporating the ultimate dynamic strength of low carbon steelis developed. Based on the agreement between the results ofthe finite element analyses and those of the empirical formula,it can be concluded that a properly modeled finite elementanalysis (FEA) can be employed with sufficient accuracy to studythe short-term dynamic burst pressures of metal cylinders.
