DTIC ADA249358: Instrumentation for Ultrahigh Strain Rate

More Book Details

Description of the Book:

This report outlines instruments acquired and fabricated at UCSD, under Grant No. DAAL03-88-G-0007, as part of the URI on Ultrahigh Dynamic Performance Materials. The URI was awarded by ARO in October, 1986. The instrumentation developed under this grant includes a computer control system for safe operation of gas gun; dedicated interferometry recording system for gas gun; an ultrasonic system; a 3OOkV flash X-ray system; an image-converter camera system capable of 20 million frames per second; a high-speed framing and streak- recording camera capable of up to two million frames per second, 85 high- resolution frames; a complete image-processing system dedicated to dynamic quantitative holography; and necessary dedicated wave-form digitizers. In addition, a novel system is developed to generate laser-induced high amplitude, short duration stress pulses, using much of the facilities which already existed at UCSD. Included in this report is a brochure entitled The Experimental Facilities of the Center of Excellence for Advanced Materials which includes brief descriptions and photographs of many of the instruments reported herein
