Abstract
This article discusses the general equation derived recently for the lattice strains which correspond to the strains measured by a diffraction method on a solid polycrystalline specimen compressed nonhydrostatically in an opposed anvil setup. The equations for the various diffraction geometries used in high pressure work emerge as the special cases of this equation. The expressions for the strain based on isotropic elastic theory (IET) available in the literature can be obtained by invoking the condition of elastic isotropy in the general equation. The equations based on IET give macroscopic strain in a specified direction, and this strain, in general, differs from the x‐ray measured lattice strain in the same direction. The predictions of the general equation have been compared with those of the equation based on IET.
