Report No. ARL-TR-4496
Authors: Jian H. Yu, Peter G. Dehmer, and James M. Sands
Date/Pages: July 2008; 36 pages
Abstract: This report describes the equipment and the operating procedure for the dynamic impact tester. It is used to evaluate armor materials and systems, such as composites, ceramics, transparent armors, and helmets. The dynamic impact system is capable of launching a projectile at speeds ranging from 50 to 1000 m/s at a target and capturing the history of impact events, such as the speed of projectile, the strain and strain rate on the target during the impact, and the spall pattern.
