Paper Abstract

An impact test system is developed by incorporating a digital imaging system with a gas-gun type impact machine. By using this system, impact perforation tests by a steel ball projectile traveling at high speed are conducted on polymer and ceramic materials, while, at the same time, consecutive images of the projectile perforating the target material are taken during the tests. Combination of the test results along with the ultra-high speed images leads to analytical modeling for estimating/predicting the perforation characteristics of these materials. It is concluded from the present study that, (1) the impact test system developed here is proven to be a powerful means to the end of this investigation, (2) the ultra-high speed photography allows visualization of such a high-speed mechanical process as an impact perforation of a target material by a projectile, and (3) the digital consecutive images are very helpful with the analytical modeling, from which semi-empirical expressions for estimating/predicting the major perforation characteristics of these materials are successfully obtained.
