Fatigue behavior of single-crystal nano-sized Cu beams
(2018) 22nd European Conference on Fracture In Procedia Structural Integrity 13. p.837-842- Abstract
- It is well-known that the response to mechanical loading of nano-sized metal structures differs from what applies to the macroscopic scale, and often non-intuitive behaviors are revealed. Here beams of square cross section, containing defects in terms of voids and loaded in fatigue with R = 0 under displacement controlled conditions, are investigated. The structures under consideration are single-crystal copper beams, chosen since such elements are common parts of a large variety of products found on the market today. The aim is to determine the resistance against fatigue failure through 3D molecular dynamic simulations. The simulations have been performed employing the 3D molecular dynamics free-ware LAMMPS.
