Damping coefficient in damping mechanisms

  1. Sep 29, 2016 #1
    Hello everyone,

    I am trying to design an element that its purpose is providing stiffness and damping. The material that I wish to use is rubber.

    My question is, how can we calculate the damping coefficient (c) for the calculation of the term c*dx/dt, when we know the loss factor of the material (for example η=0.075 for rubber) and the geometry of the element is defined.

    Thanks in advance.

    i remember to have used a damped oscillator and c can be estimated experimentally. one can see the following for measurement...
