Strain rate effects at tensile loading of single crystal Cu nano-wires

Melin, Solveig LU and Ahadi, Aylin LU (2017) International Summer School-Conference “Advanced Problems in Mechanics”
Abstract (Swedish)
It is well-known and experimentally conrmed that the mechanical re-
sponse to loading of small enough structures diers from what applies to the
macro-scale. This is valid for structures of linear measures at the nano-scale,
typically below about 50nm. In addition to pure size eects also the crys-
tallographic orientation becomes important at this scale. This study demon-
strates the mechanical response to displacement controlled tensile loading of
solid nano-sized fcc single-crystal Cu beams of square shaped cross sections.
The investigation was performed through 3D molecular dynamic simulations
using the free-ware LAMMPS. Two dierent crystal orientations and dier-
ent loading rates were considered.... (More)
