The High Pressure Equation of State of Tantalum Polystyrene, and Carbon Phenolic Determined from Ultrasonic Velocities.
Abstract
The equation of state of tantalum, polystyrene, and the composite material, carbon phenolic, was determined from experimental measurement of the ultrasonic velocities as functions of pressure and temperature. Hydrostatic pressures ranged to 150,000 psi for each material while temperatures ranged from ambient to 100C. Calculations of the pressure dependence of the bulk modulus from the ultrasonic data allowed specification of the equation of state. Comparison of the results with dynamic shock-wave experiments on similar materials shows good agreement at pressures very much higher than the 10 kbar available for ultrasonic measurements. (Author)
