Abstract The low temperature failure characteristics of two types of solid propellant are derived from the flexural tests on round bar specimens. Quantities which measure strength and variability are established and master curves expressing these quantities in terms of strain rate and temperature are determined. The method is applied to two types of propellants and failure probability contour curves are obtained for each material.
