For shock drawing of thin plates using high-speed dry-ice projectiles, it is very important to understand the dynamical deformation process of the dry-ice projectiles and plates. In the present report, high-speed photographs are taken to visualize the direct impact sequence of circular cylindrical dry-ice projectiles on a rigid wall, and the hydrodynamical pressure generated at the impact surface is measured simultaneously. Also, the shock drawing of thin plates is simulated by means of the computer code AUTODYN-2D for the same configurations as in the experiments. In the simulations, paraffin projectiles are successfully used instead of dry-ice projectiles, although the effect of sublimation of the dry-ice on the impact phenomena cannot be taken into account.
