Abstract : This report summarizes theoretical and experimental research on distributed damage growth and its effect on stress-strain behavior and on the strain distribution around macro-cracks in particle-filled rubber. Two Appendices provide details on the constitutive model, experimental determination of deformation and damage in specimens under axial straining and confining pressure, and experimental measurement of strain fields in biaxially-stressed specimens with cracks.... Solid propellant, Viscoelasticity, Damage growth, Crack growth.
