WebBe sure to warn the reader explicitly if you use this notation, and write “direction” each time. Set of directions or axes equivalent to [ hkl] under the symmetry group of the crystal; a direction or axis in the set. For example, in a cubic crystal the〈100〉 directions are [100], [010], [001], [ ¯. ¯1 ]. Plane; set of parallel planes.

The inputs to the programme were the incremental shear strain dτ and the ... Crystallography is used by materials scientists to characterize different materials. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically because the natural shapes of crystals reflect the atomic structure. In addition, physical properties are often controlled by crystalline defects. The understanding of crystal structures is an important prerequisite for understanding crystallographic defects.
