1] Dry friction or coulomb damping : In this, the damping force is constant in magnitude and opposing the motion in direction.

2] Viscous damping : In this type, the damping force is proportional to the velocity of the vibration.

3] Structural damping : This type of damping is due to the internal friction of the molecules.

4] Slip and Interracial damping : Energy of vibration is dissipated by microscopic slip on the interfaces of machine parts in contact under fluctuating loads.
