  • Using split Hopkinson compression-shear bar, the friction coefficients between GO-924 explosive and three materials including aluminum alloy, rubber, and GO-924 explosive itself were investigated under different shock loading conditions.The results show that the rules of the 3 friction coefficient curves are different.For aluminum alloy, the friction coefficient varies between 0.166 and 0.176 and is independent of impact speed; for rubber, the friction coefficient increases steadily and is sensitive to impact speed; the friction coefficient between explosives increases at first and then decreases, which is likely to relate to explosive damage.
