Stress-strain responses of five fcc crystals subjected to triaxial loading are investigated by means of pseudopotential density functional method. Particularly, the influence of superimposed transverse biaxial stresses on the maximum uniaxial stresses is evaluated for both tensile and compressive regions. The obtained results revealed that the compressive strengths (maximum compressive stresses) of all studied metals are more sensitive to the superimposed stresses than their tensile strengths. The compressive strengths were found to be increasing linear functions of the compressive transverse stresses.
