The application of the non-linear theory of elasticity to solid state problems has recently become of increasing importance. For numerical work the knowledge of the third-order elastic constants is required. The present paper compiles the various experimental methods for the experimental determination of these constants and derives, where required, the formulae for the evaluation of the experiments. We give a critical compilation of the available data on third-order elastic constants. A complete set is given for germanium single crystals (6 constants) and for polycrystalline copper and iron (3 constants).
