A study led by Assistant Professor Darren Chian Siau Chen from the Department of Civil and Environmental Engineering at the National University of Singapore's Faculty of Engineering has found that when a projectile is fired at a sand block at high speed, it absorbs more than 85 per cent of the energy exerted against it. This ability to resist the impact increases with the speed of the projectile, even at high velocities.
