Solid Propellant Cumulative Damage Program.
Abstract
A comprehensive laboratory and theoretical analysis program was conducted to provide increased understanding of linear cumulative damage concepts for solid propellants, with emphasis upon the statistical characteristics of propellant failure. Mechanism of damage studies on model materials showed that failure is controlled by a mechanical instability behavior in the binder, which is not a tearing process. The linear cumulative damage (LCD) relation and the maximum principal stress (MPS) failure criterion were described and shown to hold for uniaxial, strip-biaxial and triaxial (poker-chip tensile tests). The effects on the time-to-failure data were evaluated in terms of the superimposed pressure, relative humidity, statistical variability, aging and sensitivity to variations in the environmental test conditions.
