Ab initio study of shear strength of fcc metals: influence of normal stress

The influence of stress applied perpendicularly to a slip plane during shear deformation of crystal on shear strength is important in many deformation processes. As an example, one can consider the nanoindentation process as a combination of shear and compressive deformation in the vicinity of indentor. Previous studies suggested nearly linear dependence of theoretical shear strength on normal compressive loading. Atomistic simulations of shear deformation in fcc metals is performed using first principle method based
