Effects of Lattice Relaxation and Limiting Shear Stress of fcc Metals at High-Rate Deformation
The results of calculations of the theoretical limiting shear stress for fcc metals Cu, Ni, Ag, Au, Pd, and Pt performed using “universal” empirical potentials of interatomic interactions of the embedded-atom type are presented. The effects of lattice relaxation are shown to play an important role i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The results of calculations of the theoretical limiting shear stress for fcc metals Cu, Ni, Ag, Au, Pd, and Pt performed using “universal” empirical potentials of interatomic interactions of the embedded-atom type are presented. The effects of lattice relaxation are shown to play an important role in the formation of intermediate defect structures and lead to a considerable decrease in the theoretical yield point. Qualitative effects of the “anti-adiabatic” influence on the material ultimate strength under conditions of high-velocity loading are discussed. |
