ELASTIC CONSTANTS OF SINGLE CRYSTALS
H. P. R. Frederikse
This table gives selected values of elastic constants for single crystals. The values believed most reliable were selected from the original literature.
The substances are arranged by crystal system and, within each system, alphabetically by name. A reference to the original literature is given for each
value; a useful compilation of published values from many sources may be found in Reference 1 below.
Data are given for the single-crystal density and for the elastic constants cij, in units of 1011 N/m2, which is equivalent to 1012 dyn/cm2.
