American journal of optometry and archives of American Academy of Optometry, 1969
ABSTRACT A ballistic method for testing spectacle lenses in safety frames is presented. Three categories of prescription spectacle lenses (industrial and dress thicknesses, tempered glass, and dress thickness allyl resin plastic), and one category of plano spectacle lenses (industrial ...

Ballistic range and aerothermodynamic testing

Journal of Aircraft, 1991
Recent interest in hypervelocity vehicles requires an increase in our understanding of aerothermodyn amic phenomena. Tests conducted in ground-based facilities will be used to better our understanding of the physics of hypervelocity flight and to verify computer models that will be used to predict vehicle performance in this environment.

Ballistic Testing of Motorsport Windshields

SAE International Journal of Transportation Safety, 2013
<div class="section abstract"><div class="htmlview paragraph">Since its inception in 1948, NASCAR® (National Association for Stock Car Auto Racing, Inc.) has continually strived to promote and improve driver, crew and spectator safety. As the vehicles used in NASCAR have changed over the years, their windshields have evolved also.

BALLISTIC TESTS OF BULLET IMPACT INTO WATER

Proceedings of the 32nd International Symposium on Ballistics, 2022
Research works described in the paper, were performed within the framework of the project: Laboratory stand for stopping high-energy projectiles (Agreement no. DOBBIO10/ 04/02/2019). Methods used nowadays in forensic laboratories allow to stop some kinds of projectiles with degree of deformation which lets to use them for comparing traces to bullets ...

Armor Plate Ballistic Testing

1944
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, 2006
This 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.

Improved Ballistic Test and Evaluation Methodology

2006 IEEE Systems and Information Engineering Design Symposium, 2006
Ballistic 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, 1977
How 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, 1979
Ballistic 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.
