Abstract：An experimental and the finite element analysis (FEA) on the dynamic response of double-layer steel pipes to internal blast loading are presented in this paper. Both effects of wall-thickness-arrangements of double-layer steel pipes and mass change of TNT charges were discussed. The results indicate that compared to the change of outer pipe thickness, inner pipe thickness change does more significant effect on the shock resistance performance of double-layer steel pipes under the studied charge mass, but the effect reduces with the increasing of charge mass. Meanwhile, inner pipe thickness change does especially function on energy absorption. However with the increase of charge mass, energy dissipation in outer pipe increases faster than in inner pipe.
