In this paper, the failure of a pultruded glass fiber reinforced composite tube subjected to axial impact load transmitted by a small attached mass exposed to blast load is discussed. A numerical simulation is developed with LS-DYNA and is validated with experiments carried out on a ballistic pendulum by comparing the transmitted impulse by the explosive and crushed distance of the composite tube. The air blast is simulated using Eulerian multi–material formulation. The simulation shows good correlations with the experiment.
