Abstract:

An investigation of the disk method and bar method for evaluation of damping treatments was undertaken to determine whether differences in test results obtained by the two methods of test were inherent in the method of test or were due to variation in sample material. Tests performed on ML-D2 damping treatment showed that the disk method gave higher damping at frequencies up to about 6 kc. This difference ws attributed to edge effects which ar tronger in the disk method of test. At frequences above about 6 kc, inconsistencies in the data were so large that differences due to test method could not be separated. Author
