As noted in Section 3.15, for single crystals of some substances

As noted in Section 3.15, for single crystals of some substances As noted in Section 3.15, for single crystals of some substances, the physical properties are anisotropic; that is, they are dependent on crystallographic direction. One such property is the modulus of elasticity. For cubic single crystals, the modulus of elasticity in a general [uvw] […]
