DIRECTIONS AND PLANES
There are a few basic rules for describing
geometry in and around a unit cell.
Lattice positions: distances expressed as
fractions or multiples of unit-cell dimensions.
For example, the body-c

Perhaps the simplest questions
that a design engineer can ask
about a structural material are:
1) How strong is it?
2) How much deformation must I
expect given a certain load?
