Quantifying the interface deformation mechanisms in nanostructured metals with atomic simulations and continuum field representations
… nanolayered metals subjected to out-of-plane tension are investigated by molecular dynamics simulations. The results show that the initially planar Cu–Ag nanolayers abruptly become wavy at a critical tensile strain. High stress concentrations subsequently develop at the summits and valleys of …

Study of Nanowires Using Molecular Dynamics Simulations
… consisted of straining the nanostructures in tension at a strain rate of 3.3 x 10^8 s⁻¹. Grain boundary movement was recorded to quantify grain boundary velocities and grain growth. It was shown that during deformation, there is interplay between dislocation-mediated plasticity and grain …

Modeling mechanical properties – linking atomistics to continuum
… theory. The experiments involve uniaxial tension and compression tests on: (a) single crystals of low stacking fault energy Co-33%Ni alloys, (b) polycrystalline nano-twinned Ni-x%Co alloys (x = 1, 1.62, 2.9 and 5.6), and (c) equiatomic NiTi shape memory alloys. The reason these materials …
