Source of propulsive energy of solid rocket is integral part of total structure; accordingly, reliability of system will depend on how well one can predict integrity of propellant grain structure under various environmental conditions; problems of fatigue or endurance of solid propellants are discussed from viewpoint of both internal (molecular) structure and engineering mechanics; importance of developing failure criteria and methods of analysis for such structures under extended dynamic loading indicated; pertinent research areas of primary importance are shown.
