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.
