The development of efficient explosion resistant containers requires knowledge of dynamic material properties and the ability to simulate both the explosive loading and the corresponding structural response. A lightweight, transportable containment vessel could be used as an integral part of the response to bomb-related terrorist activities. Several composite vessel designs have been developed by the Russian Federal Nuclear Center (RFNC-VNIIEF) and explosive experiments have been performed on open ended cylinders for the purpose of benchmarking analysis methods. The objective of the work presented here is to determine the mechanical properties of the cylinder materials and to investigate different methods for computational simulation of the cylinder response to blast loading. The open ended cylinders are made from a basalt fiber-epoxy composite material with and without a steel inner liner. Computational simulation is performed using LS-DYNA. The predicted response of the composite structure matches experimental data closely for three different test cylinder configurations.
