Original Abstract

The influence of stress applied perpendicularly to a slip plane during the shear deformation of a crystal on the ideal shear strength was studied for <110>{111} and <112>{111} slip systems from first principles. Previous empirical studies for Lennard-Jones crystal suggested nearly linear dependence of the shear strength on the normal tensile and compressive loading. Our ab initio results verified the linear dependence for 6 fcc metals.
