An Approximation Method for the Determination of the Elastic Constants of Single Crystals

Abstract

Plane elastic waves traveling in an arbitrary direction in a crystal are, in general, neither transverse nor longitudinal and in fact show polarization angles up to 11° in nickel. A method for deducing the elastic constants of a cubic crystal is well known. The method is here extended to other crystal classes where the method may be used in order to deduce all the elastic constants of a crystal.
