The damage state in composite solid propellant specimens subjected to different loading histories was investigated using acoustic imaging techniques. The acoustic imaging data was analyzed to delineate the damage field in the specimen and to generate contour plots of the damage intensity. The results of these analyses were compared and the effects of the loading history and crack length on damage characteristic are discussed.
