This paper is concerned with the forced vibrations of case-bonded solid propellant grains. Special attention is paid to the interaction between the thin elastic shell case and the thick-walled propellant cylinder. The effects of material damping in the propellant are explored. Frequency-response functions are computed, which can be used for analysis in situations where the loading is arbitrary deterministic or random stationary.
