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 theoretical  strength is evaluated for uniaxial tension and compression. The compressive strengths were found to be increasing linear functions of the compressive transverse stresses.
