Design Criterion for Ramp Wave Generator

A design criterion for ramp wave generator is derived in this paper, which may be expressed as -[(2/3)+(g/2)] or -[(2/3)+(g/2)](cV/c2) (here is Grneisen coefficient, thermal expansion coefficient, c hydrodynamic sound speed, cV specific heat capacity at constant volume, g a material constant). Experimental results of a glass-ceramic sample showed that it may be used as a ramp wave generator, in which a shock wave could be transformed to an acceleration wave with front rise time of 800 ns at the position of 20 mm thickness.
