Under this support the following facilities have been developed: (1) Small broached gas gun, capable of both normal and oblique plate-impact testing, together with both displacement and velocity interferometric facilities. (2) Large gas gun for normal plate impact experiments. (3) Compression Hopkinson bar with dedicated data acquisition and analysis system. (4) Tension Hopkinson bar. (5) Torsion Hopkinson bar. (6) Miscellaneous data acquisition systems including a Le Croy and a flash X-ray unit. These facilities were designed and constructed whenever possible, at UCSD. They include a number of innovative high-strain-rate testing techniques. 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 herewith. 收起
