The Influence of Superimposed Biaxial Stresses on the Ideal [100] Strength of Selected FCC Crystals

, the influence of superimposed transverse biaxial stresses on the <100> theoretical strength is evaluated for uniaxial tension and compression. The compressive strengths were found to be increasing linear function...
