This paper considers influence of small geometrical imperfections, such as out-of-roundedness and eccentricity, on the magnitude of the added (apparent, virtual) mass for a rod vibrating in acoustic fluid contained within a rigid cavity. Using the perturbation of boundary conditions method derived are simple formulas allowing qualitative and quantitative analyses for several types of imperfections.
