Forced Vibrations of Two Masses on an Elastic Half Space

Abstract

The paper gives a theory for the response of two periodically excited masses with circular bases attached to the surface of an elastic half space. Results for two geometrically identical cylindrical masses, excited by a vertical harmonic force applied to one of the masses, illustrate the effect of the presence of a second mass upon the response of the excited mass and the conditions for which the response of the second mass is significant.
