Description
| - Theoretical tensile strength under isotropic (hydrostatic) loading of copper crystal is evaluated as a stress at the onset of dynamical instability in the lattice. In this paper, the mechanical stability is assessed by using phonon spectra that are calculated for different values of strain from first principles. The pseudopotential plane wave code Abinit, based on the density functional theory, is used for this purpose. Dynamical matrices that are used to construct dispersion curves are calculated by means of linear response method. The obtained results are consistent with the analysis of elastic stability.
