The x axis is the [100]

**direction**; the — y axis is the [OlO]**direction**. A full set ofequivalent

**directions**is denoted this way: (uvw). In cubic crystals a**direction**[uvw]is perpendicular to a plane (uvw) having the same indices, but this is not

generally true in other crystal systems. The positions of points in a unit cell are

specified in terms of lattice coordinates, in which each coordinate is a fraction of

the axial length, a, b, or c, in the

**direction**of the coordinate, with the origin takenat the corner of ...

Thus the dilation is (4.12) & = AV/V = eZI + evv + elt. SHEARING STRAIN We may

interpret the strain components of the type dv du e*v = T~ + T dx dy as made up of

two simple shears. In one of the shears, planes of the material normal to the x

axis slide in the y

defined as the stress. There are nine stress components: Xx, Xy, XIt Yx, Yv, Yz,

ZX, Zy, ...

The excess energy required in the hard

**direction**is the anisotropy energy. As anexample of anisotropy energy we may consider cobalt, which is a hexagonal

crystal. The
