Damping capacity is a mechanical property of materials that measure a material's ability to dissipate elastic strain energy during mechanical vibration or wave propagation. When ranked according to damping capacity, materials may be roughly categorized as either high- or low-damping. Low damping materials may be utilized in musical instruments where sustained mechanical vibration and acoustic wave propagation is desired. Conversely, high-damping mate… WebDec 1, 2001 · Metal composites provide vibration damping due to the interface between reinforcement and matrix, leading to enhance the damping capacity and stiffness which is responsible for vibration reduction ...
