abstract

This paper presents finite element modeling of a lightweight composite vessel for blast containment purposes. The vessel has a steel liner that is internally reinforced with throttles and gusset plates and wrapped with a basalt fiber/epoxy composite. The vessel design is fairly complex, including many geometric details, and several different materials. The objective of this work is to determine an efficient analysis procedure that can be used in an iterative optimization process. Analysis approaches using various combinations of element type, material models, and geometric detail are explored. Finite element results are compared to experimental data. Accuracy and efficiency are compared for all cases and a suitable analysis method is recommended.
