High-Strain Rate Mechanical Response of Green Insensitive Munitions Gun Propellants

Report No. ARL-TR-2755
Authors: Michael G. Leadore
Date/Pages: June 2002; 29 pages
Abstract: Four lots of green insensitive munitions gun propellants were tested in uniaxial compression. A production lot of M14 that is currently used in the M865 training round was also tested for comparison purposes. The materials were tested while conditioned at 21?, 63?, and !32 ?C. The materials were taken to ~60% strain using a deformation rate of 1.3 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.
