Abstract
The five independent elastic constants of beryllium have been determined with the pulse echo technique at a frequency of 10 Mc/sec. The values extrapolated to 0°K are C11=29.94±0.06, C33=34.22±0.12, C44=16.62±0.05, C12=2.76±0.08, C13=1.1±0.5 in units of 1011 dyne/cm2. Voigt averaging and Reuss averaging of the single crystal elastic constants give excellent agreement because of the small magnitude of the nondiagonal elements, C12 and C13. The averaged values compare favorably with previous data from polycrystalline beryllium.This publication has 9 references indexed in Scilit:
