Cauchy-Born rule

Cauchy-Born rule

The Cauchy-Born rule or Cauchy-Born approximation is the statement that in an object subject to a small strain the positions of the atoms follows the overall strain of the material. This approximation generally holds for FCC and BCC crystals, for complex lattices such as diamond, the rule has to be modified to allow for internal degrees of freedom between the sublattices.
