An alternative method to the identification of the modal damping factor based on the dissipated energy
A new method for the identification of the modal damping factor is presented. The starting point is the dissipated energy per vibration cycle. Identification is made directly from measured Frequency Response Functions. It is a simple and easy to implement method. It is accurate for lightly damped structures with spaced mode shapes.
