Damping Models and Measures

• Damping refers to dissipation of energy from a vibrating system.
  
  
• Damping force magnitude is generally smaller than elastic and inertia forces.
  
  
• Even if damping force is smaller, it is important for controlling vibration particularly near resonance.
  
  
• A large range of physical mechanisms are involved in this process. some in the level of molecular rearrangement, while some related to macro scale effects like energy transformation.
