Abstract
This report describes studies on gas-gun-based or pulse laser-induced shock waves in condensed materials with relatively high compressibility like polymers and bio-related materials. We have studied phenomena of the pressure range less than several GPa. Topics covered include (i) development of precision shock Hugoniot measurement methods developed for the present pressure region, (ii) discussion of several experimental results and (iii) some applications to medicine and initiation of high explosive charge.
