Particle Impact Damping: Influence of Material and Size. (December 2003) Kun Saptohartyadi Marhadi, B.S., Texas A&M University Chair of Advisory Committee: Dr. Vikram K. Kinra In this study, particle impact damping is measured for a cantilever beam with a particle-filled enclosure attached to its free end. Many particle materials are tested: lead spheres, steel spheres, glass spheres, tungsten carbide pellets, lead dust, steel dust, and sand. The effects of particle size are also investigated…
