We present a new framework to quantify the effect of hydrogen on dislocations using large
scale three-dimensional (3D) discrete dislocation dynamics (DDD) simulations. In this …

A model is developed to describe the grain size effect on elastoplastic behavior of ultrafine
grained (ufg) and nanocrystalline (nc) materials using a self-consistent approach. The grain …

Understanding the mechanical properties and deformation characteristics of nanoscale
metallic nanopillars and wires is a significant concern for designing reliable small devices …

Recent experimental and theoretical studies indicate the “external geometry” and “internal
structure” are the controlling factors to characterize the size-dependent plastic flow for micro …

摘要体心立方(BCC) 金属在亚微米和纳米尺度表现出不同于块体粗晶尺度的力学性能,
包括高屈服强度和大延展性. 这些突出性能使其不仅可用于微米, 纳米甚至原子尺度的器件 …

Cu–Nb nanocomposites are good candidates to be used in high-pulsed magnetic fields due
to their high strength along with high electrical conductivity. It is important to characterize the …
