Improved Ballistic Test and Evaluation Methodology
2006 IEEE Systems and Information Engineering Design Symposium, 2006Ballistic test and evaluation of body armor is of great priority for the US Army to meet current operational needs. The current experimental design process centers on standardized threat level classifications and a baseline ballistic limit velocity, V50; both measures originate from the National Institute of Justice circa 1979. The measures are complex,

Test of the ballistic hypothesis of movement and the ‘point of no return’
Nature, 1977How long does it take to stop or modify a movement once it has begun? Where there is an error in producing an action as intended (usually because of control-display incompatibility) subjects may correct it in less than their normal reaction time (RT) by proprioception1 or efference-copy monitoring2—4.

Ballistic Pendulums and Dynamic Testing of Clays
Journal of the Geotechnical Engineering Division, 1979Ballistic pendulums provide simple and effective means of testing clays at constant rate of strain. Tests were performed at strain rates of 1,400%/sec and 2,300%/sec. Increasing stiffness of stress-strain response reported for lower strain rates (up to 0.17%/sec was found to occur for higher strain rates as well as for the horizontally oriented samples.
