The Effect of Mass Loading on a Stiffening Rib.

Abstract

In the scattering of an acoustic wave incident upon a rib-reinforced plate, the effect of the rib can be characterized by a pair of impedances. One of these impedances is associated with the longitudinal vibrations of the rib, and the other impedance is associated with the flexural vibrations of the rib. This report calculates the impedances and the effect of mass loading on these impedances. The calculations are done for a thick or Timoshenko-Mindlin rib which is fluid loaded with the rib immersed either in water or air. (Author)
