| dc.description | Abstract: Impact tests were performed to investigate survivability of proposed BMD structural materials to fallout debris from a nuclear surface burst. The materials evaluated included: 1.0-in. thick 060-T651 aluminum; 2.5-in. thick epoxy fiber glass; 0.5-in. thick T-1 steel; 24-in. thick concrete. A specially designed powder gun was utilized to project sandstone missi1es weighing 10-, 25-, and 50-lb each at the specified targets. The impact velocity for the 10- and 25-lb projectiles was nominally 300 fps and the 50-lb projectiles impacted at velocities near, but exceeding, 200 fps. The damage incurred in the targets as result of impact was negligible. Thinner plates (0.375- and 0.25-in. thick) of T-1 steel and mild steel were impacted to determine the penetrating capability of a 50-lb sandstone cube. Both 0.25-in. thick plates were penetrated while the 0.375-in. thick plates were only dented. A fiber glass panel 0.94-in. thick was also penetrated by the 50-lb projectile. These tests indicate that sandstone debris in these sizes is a minimal threat to BMD structures although stronger material such as granite has shown considerably more penetration capability in previous tests at MDAC. It is also apparent that previously established predictive data for granite would not apply for materials with less strength than granite such as sandstone. | - |
