Material and Structural Damping for Vibration Control 600055

THE INCREASING importance of near-resonant vibrations and the role of system damping in their control is discussed. The various component parts of system damping are classified and analyzed within the framework of:
  1. 1.
    Hysteretic damping within the structural materials.
  2. 2.
    Structural damping associated with (a) interface slip or Coulomb friction, and (b) shear strain in an adhesive layer at an interface.
Each of these mechanisms is analyzed to emphasize the factors important in the utilization of damping as an engineering property. Particular attention is paid to analytical concepts for maximizing the shear damping in an interface adhesive by design optimization procedures.*
