A formulation for the structural intensity in a thin, point-driven cylindrical shell is presented, as well as the corresponding energy balance relationships. These representations are then applied to real, experimental data for the presentation and analysis of fluid--structure interaction. A movie will be presented that displays, simultaneously, the instantaneous structural intensity within the cylindrical shell, as well as the instantaneous intensity in the surrounding fluid due to a transient pulse delivered by the point driver. The contributions of the individual components comprising the formal representation of the structural intensity (i.e., longitudinal, in-plane shear, etc.), as well as the mechanism of fluid--structure interaction in the very near field, will be discussed in detail from the point of view of instantaneous energy flow.
