Dynamic compressibility, release adiabats, and the equation of state of stilbene at high energy densities

Abstract

The shock adiabat of porous stilbene (1,2-diphenylethylene) up to the pressure P = 41 GPa and the dynamic compressibility of this material in reflected shock waves up to 77 GPa are studied experimentally. The run of the expansion isentropes of stilbene down to 0.1 GPa is determined. The experimental findings are used to construct a semi-empiric equation of state of stilbene for a wide range of high-energy states.
