A general method is presented for obtaining the electrostatic contributions to the first-, second-, and third-order Brugger-type elastic constants of metallic and ionic structures. The electrostatic energy per unit initial volume of a homogeneously deformed lattice is determined by the Ewald-Fuchs method. General equations for the Brugger elastic constants are found by taking Lagrangian strain derivatives of this energy expression. Internal-strain contributions, which occur for nonprimitive structures, have been included. Results are tabulated for six metallic and five ionic structures.
