Abstract

Abstract

In this paper we investigated the dynamic response of thin-wall circular tubes under lateral blast loading based on experimental research, theoretical analysis and finite element simulation. We studied the dynamic responses of the tubes under explosion using the ballistic pendulum system and analyzed the deformation modes of the thin-wall tubes, and based on the foundation beam model, established a theoretical model of the mid-span deflection of the circular tube under lateral blast loading and made it dimensionless. We also analyzed the influence of the geometric parameters of the circular tube on its deformation mode and mid-span deflection using finite element simulation and compared it with the theoretical prediction. The results show that the deformed area and the mid-span deflection of the circular tube increase with the increase of the TNT mass. The length-to-diameter ratio, wall-thickness of the circular tube and the loading impulse all have a great influence on the mid-span deflection of the circular tube. The theoretical prediction and the numerical results are both in good agreement with the experimental results.
