• To discuss the elastic properties of aluminum, the variations of the crystal energy at OK with the (100) lattice deformations are evaluated by means of the pseudopotential methods based on the model potential proposed by the authors previously. A distinction is made between the mechanical behavior of a face centered cubic (fcc) lattice in (100) loading (i.e. transverse stresses are zero) and in (100) deformation (i.e. transverse strains are zero). The fcc-bcc transitions and the elastic instabilities associated with the deformations are briefly discussed. Some elastic constants of aluminum at OK are calculated. The stress-strain relations for large elastic strains up to the theoretical tensile strength are presented.
