DETERMINATION OF SHOCK EQUATION OF STATE PROPERTIES OF CONCRETE USING FULL-SCALE EXPERIMENTS AND FLYER-PLATE-IMPACT TESTS

摘要

Two different and independent shock compression experiments have been performed to determine equation of state (HUGONIOT) properties of concrete. The techniques used in the present study offer on the one hand full-scale detonation experiments wherein pressures were directly measured in the affected concrete body with carbon resistor gauges. And, on the other hand, flyer-plate-impact tests where subsequent velocity histories were monitored by a VISAR and the related pressures and densities evaluated by means of the conservation equations. The concrete specimens have been produced in the same series and the experiments performed at the same time. Pressure-density data are reported from both methods through the elastic range up to 15 GPa.
