Effects of Atmospheric Turbulence on Ballistic Testing
Journal of Applied Meteorology and Climatology, 2008AbstractThe effects of atmospheric turbulence on munition target scatter are determined from numerical simulations of ballistic trajectories through many realizations of realistic simulated turbulent wind fields. A technique is evaluated for correcting for the effects of turbulence on ballistic testing procedures by using a line of sonic anemometer ...

Abstract : The fundamentals are presented for a rational system of armor plate ballistic testing. The desirable properties of armor are first discussed. These are (1) high resistance to penetration, (2) freedom from back spalls, (3) freedom from cracking (shock failure).

Ballistic Impact Testing of Composite Structures
Earth & Space 2006, 2006This article deals with techniques which have been developed to study the behavior of composite materials and structures under high speed ballistic impact conditions at the NASA Glenn Research Center (GRC) Ballistic Impact Facility. The techniques include launching systems, fixture methods, imaging systems and instrumentation systems.

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.

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,

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.
