Finding damping coefficient of material

  1. Jul 22, 2010 #1
    i have found the damping factor of a plate from experimental vibration.

    how can i find the damping coefficient of the material of the plate

    One of the more easy methods is the log decrement method. Basically, you displace the plate, release and measure the displacement as a function of time. The displacement should damp logarithmically which can give you the damping coefficient.
