SONIC DETERMINATION OF ELASTICS CONSTANTS IN GRAPHITE

PDF Version Also Available for Download.

Description

The operation of a Magnatest Type FM-500 Elastomat instrument, the detection and recognition of the resonant frequencies of a sample, the methods and formulas for the calculation of the elastic moduli from the resonant frequencies, and results obtained from testing several different materials and sample shapes are discussed. The accuracy and reproducibility of the sonic modulus method for graphite was found to be very good. The fundamental flexural resonance was reproducible to within 0.2%, with the reproducibility of the high resonances decreasing to about 0.5%. The data are tabulated. (P.C.H.)
