摘要: Planar shock experiments were conducted on granular tungsten carbide (WC) and tantalum oxide (Ta{sub 2}O{sub 5}) using the Z machine a 2-stage gas gun. Additional also nearly fully dense form of Ta{sub 5}. The WC yield some highest pressure results for materials obtained to date. Because high distention 5}, pressures significantly lower, but very temperatures generated led large contributions thermal energy material response. These demonstrate that can be used obtain accurate data materials. 5} utilized in making improvements P-{lambda} model pressures; is found capture not only gun those from laser low density aerogels. are illustrate an approach generating equation state limited coming nanoindentation. Although EOS this manner rather simplistic, it gives reasonably good results.
