Experimental high pressure equation of state of a very fast burning gun propellant

OSTI ID:6504057
We present experimental data on the pressure-volume, compressional and shear wave speeds, and failure strength of an 88% TMD, very fast burning gun propellant. The measurements are carried out in the range 0.1 to 400 MPa at a stress rate of 0.1 MPa/s and at room temperature. The mechanical EOS is dominated by the elastic-plastic response of the pore structure, although precise analysis is complicated by viscoelastic effects with time constants comparable to experimental times. These measurements represent some of very few experimental data available for constitutive relations, and the need for other laboratories to undertake similar experiments is emphasized.
