The Relationship of Traditional Damping Measures for Materials with High Damping Capacity.
Abstract
Simply stated, damping is the dissipation of energy in vibrating systems which results in either the control of the amplitude of oscillations or their eventual decay. In mechanical systems damping can be classified as passive or active. Active damping uses externally applied feedback control forces to limit the deformation and motion of large structural configurations. Passive damping makes use of properties which are inherent to the system and which arise from energy dissipation taking place within stressed elements of a vibrating system or from energy being imparted to a surrounding dissipative medium. The passive damping which is of interest in this discussion involves mechanically stressed materials or structural elements and the energy dissipation associated with cyclic strain or stress.
