Mechanical Response of Gun Propellant Beds at Low Strain Rates

Abstract

A device was designed and built to measure the applied transmitted and central stresses within propellant beds of JA2, M30, and M43 gun propellants during compaction. It was observed that the stress at the center of the beds matched the average applied stress in form and magnitude in all but one instance. The velocities of mechanical disturbances were calculated and found to range from 50 to over 300 m/s. A strong correlation was demonstrated between the single grain and bed modulus values.
