A simple test procedure was used to determine the total damage in a propellant that accumulates during a tensile test from 0% strain to failure. Damage energies of two propellants were measured at various temperatures and straining rates, and Williams‐Landel‐Ferry shift procedures were applied to the results. The reduced master curves for the total damage energy at failure are used to compare the failure behavior of the two propellants.
