Mechanical Properties of Aerojet, Thiokol, and JA2 High-Energy Gun Propellants at 1.5 m/s Deformation Rate

Five lots of high-energy gun propellants were tested in uniaxial compression at temperatures of 21 deg, 63 deg, and - 32 deg C. The materials were taken to 60% strain using a deformation rate of 1.5 m/s. The stress at failure, strain at failure, compressive modulus, failure modulus, incremental ener...

Description
Summary:Five lots of high-energy gun propellants were tested in uniaxial compression at temperatures of 21 deg, 63 deg, and - 32 deg C. The materials were taken to 60% strain using a deformation rate of 1.5 m/s. The stress at failure, strain at failure, compressive modulus, failure modulus, incremental energy density, and the fracture assessment values were recorded for each test. --Original contains color plates: All DTIC reproductions will be in black and white.
