Combinations of third‐order elastic constants of zinc and cadmium

摘要

Deviations from Hooke's law are caused by the third‐order elastic constants. These deviations have been measured for one orientation of cadmium and two orientations of zinc filamentary crystals (whiskers). Expressions for these deviations have been derived and used to calculate values of the linear combinations of third‐order moduli. The experimental values of the deviations for zinc are compared with values calculated from published third‐order constants.
