Atomistic simulations of the graded residual elastic fields in metallic nanowires

open access: yesResults in Physics, 2021
The local inhomogeneity of bonding environments in nanomaterials should lead to non-uniform distributions of the surface-induced residual stress and strain (residual elastic fields), which is inconsistent with the conventional assumption of uniform ...
