XIII. A calculation of the elastic constants of aluminium

Abstract

Summary A calculation is made of the elastic constants of aluminium which correspond to pure shears without change of volume, and an explanation is given for the fact that aluminium crystals are almost elastically isotropic. Conclusions are drawn about the nature of the density of states near the Fermi surface, and it is shown how the elastic constants may be expected to depend on electron concentration in aluminium solid solutions.
