DOI: 10.1016/j.actaastro.2019.04.015
Abstract: Abstract The responses of polyimide film hypervelocity impacted by aluminum micro–flyer are studied through numerical and analytical methods. By combining the conservation equations (mass, momentum and energy) with Rankine-Hugoniot and Mie-Gruneisen equations, a mathematical solution… read more here.
