Rcsponse of Large Elastic Bodies to Vibratory Forces on Small Areas

摘要

The purpose of this study is to find a rational basis for the prediction and control of the vibratory behavior of structures and machine foundations in the acoustic frequency range (circa 1-10 kcps). IN these frequencies, for ordinary structures, a lumped parameter or even technical beam theory approach does not appear to be suitable. Various transmission line effects seem to become important, and the details of the boundary conditions have a significant effect.
