Measurement of the flexural damping capacity and dynamic …

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… WebMay 18, 2024 · The use of metal foams for damping vibrations of mechanical structures has found interesting applications in machine tools and its components.
