Generally pure metals and its alloys may have fairly good mechanical properties but falls short in damping properties.
Introduction Damping properties of the material aids in absorbing and dissipation of mechanical vibrations during cyclic loading.
Recently, it has been reported that the damping capacity of AMCs is influenced by several factors [7, 8].
Smaller the size of the particle greater will be the damping properties.
