Experimental and numerical study of pultruded composite tubes under blast loading

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.
