The molecular-dynamic research of heterostructure interface influence to the mechanical properties

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.

In the work it is presented the results of molecular-dynamicresearch of the uniaxial tension of nano-length scale copper­-silver heterostructure, and also the pure copper nanocrystal on the atomic level. It was realized the relults comparison, it was revealed the influence of the interface on the results, it was found the critical deformation value. If the deformation become greater then critical one the heterostructure plastic modification takes place. During external effect it is revealed the formation such structural modifications as Luders-Chernov stripes.
