Dynamic Methods for Determining the Elastic Constants and their Temperature Variation in Metals
SourceIn dynamic measurement of the elastic constants, the specimen is part of a vibrating system. An introduction to the theory is given and the various methods, ranging in frequency from a fraction of a cycle to 30 megacycles per second, arc critically reviewed. Dynamic methods are capable of giving precise results and arc more convenient than static measurements if the sample is small, brittle, has large creep effects, or if knowledge of the elastic constants as functions of temperature is desired. In most dynamic methods the internal friction of the sample may be measured in the same apparatus. Besides giving engineering information, dynamic-elastic measurements have proved valuable for investigating phenomena in metals.
