Fig.1. Schematics of dependence of shear modulus on orientation (l—the unit vector along primary orientation, m—the unit vector along secondary orientation, θ—the polar angle, ?—the azimuth angle, χ—the angle between m and line projected from l on horizontal plane then projected on the plane normal to l )
(a) definition of primary and secondary orientations in crystal coordinate system
(b) the relation between orientations and specimen geometry
