Abstract
A procedure for measuring the viscous damping of relatively
large plate material (up to 40 inches x 14 inches x
2
inches) was developed utilizing the Hewlett-Packard 5451C
Fourier Analyzer and impulse hammer technique under very low
stress conditions. Testing environment can be lab air or
nondistilled water in the temperature range from 30° F to
90° F.
The test procedure includes modal analysis that is
expandable to other geometric shapes and varied material
such as high damping alloys and composites both metallic
and non-metallic.
