Measurement of damping in structures by the power input method
An experimental technique for determining the internal loss factors (damping) of structures was studied. The power input method (PIM) coupled with the use of a laser vibrometer allowed for quick, and accurate measurements of loss factors of flat panel type structures. The effectiveness of this method was shown through a case study involving laminated and tempered vehicle glass windows.
