DAMPING BY UNCOUPLED PARTICULATE COMPOSITES
Large damping can be achieved by suitable design of a
composite material which contains a significant volume fraction of freely
vibrating particles in internal cavities of its matrix.An approximate analysis
of the damping behavior of such a materiel is presented. It is shown that the
damping varies linearly with amplitude, inversely with the first power of the
distance of motion and with the second power of (1-k), where k is the
coefficient fo restitution
