The Peierls stress required for a single dislocation to glide in a perfect crystal is considered
one of the most important properties controlling plastic deformation of metals. Values for the …

In order to quantitatively predict Peierls stress, a semi-discrete variational Peierls-Nabarro
model is improved by incorporating an additional gradient energy term into the energy …

We introduce a novel approach to calculating the Peierls energy barrier (and Peierls stress)
based on the analysis of the dislocation migration dynamics, which we apply to 1/2a⟨ 111⟩ …

We have computed Peierls stresses of dislocations in a variety of crystals by applying a
simple discretized Peierls–Nabarro model of the dislocation using the calculated ab-initio γ …

The line tension $\Gamma $ of a dislocation is an important and fundamental property
ubiquitous to continuum scale models of metal plasticity. However, the precise value of …

We demonstrate that the straightforward application of the nudged elastic band (NEB)
method does not determine the correct Peierls barrier of 1/2< 1 1 1> screw dislocations in …

The recently formulated constrained nudged elastic band method with atomic relaxations
(NEB+ r)(Gröger R, Vitek V. Model Simul Mater Sci Eng 2012; 20: 035019) is used to …

The Peierls barrier measures the lattice resistance to dislocation glide in crystalline solids.
We use the nudged elastic band (NEB) method to calculate the Peierls barriers for screw …

Peierls stress (τ p) of face-centered-cubic (FCC) structures from the Peierls-Nabarro (PN)
model calculation is extremely sensitive to the input parameters including the shear modulus …

We review the major efforts that improve the accuracy of Peierls-Nabarro (PN) model in
predicting core structure and Peierls stress, and recognize that the nonlocal atomic …
