Abstract

The Hugoniot of transparent Polymethylmethacrylate (PMMA)1) has been obtained in the pressure range from 20 to 80 kilobars. The Hugoniot has been deduced by measuring the shock velocity and the shock-induced free surface velocity of the PMMA plate. The present paper describes experimental techniques in which copper flyer plates have been accelerated by a powder gun for shock compression of the PMMA plates and a high speed streak camera has been employed to observe motions of a shock front and a free surface. The present techniques have proved to be usable for measuring the Hugoniots of transparent materials with relatively high accuracy. A small discontinuity appeared in the shock velocity-particle velocity Hugoniot obtained. This might suggest the existence of a phase change.
