Erratum: Acoustic time-dependent energy from force excited fluid loaded elastic shell/panel structures via a generalized modal radiation impulse response approach [J. Acoust. Soc. Am. 149(4), 2865–2876 (2021)]

The use of impulse-response photoacoustic signals to monitor time-dependent changes in physicochemical systems is described. The diffusion of a dye through a polymer and the effect of a herbicide on a plant leaf are used to demonstrate the viability of the technique.

The dynamics of a viscous particle surrounded by an elastic shell of arbitrary thickness freely suspended in a general linear flow field is investigated. Assuming the unstressed shell to be spherical, an analysis is presented for the case in which the flow-induced deformation leads to small departures from sphericity. The general time-dependent evolution of shape is derived and various special cases (purely elastic sphere, rigid and gaseous interior, elastic membranes) are discussed in detail. It is found that for steady-state flows the equilibrium deformations are absolutely stable and depend only upon the shell thickness, although the rates at which they are attained show the effect of the inside viscosity, too.
