Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …

A comprehensive atomic-level simulation study has been made of interactions between a
moving edge dislocation and copper precipitates that are initially coherent with the body …

Neutron irradiation of low-copper reactor pressure vessel steels containing manganese and
nickel gives rise to microstructural changes and a deterioration of mechanical properties …

Atomistic simulations of the interaction of a screw dislocation in α-Fe with different size bcc
Cu precipitates suggest two plausible strengthening mechanisms. For precipitate diameters …

Molecular dynamics (MD) and molecular statics (MS) simulations have been performed to
simulate the motion of a screw dislocation and its interaction with voids in irradiated body …

In this article, vehicle handling behavior of a nonlinear four-wheel vehicle system is studied.
Bifurcations with respect to vehicle speed and roll moment distribution are examined for …

Nano-scale defect clusters, such as voids, dislocation loops, stacking-fault tetrahedra and
irradiation-induced precipitates, are produced in metals by irradiation with high-energy …

It has been well known that the plastic deformation behavior of metals are governed by the
motion of dislocations. Dislocation motion is resisted by lattice defects, including impurity …

The stress required to deform a perfect crystal to its elastic limit while maintaining perfect
periodicity, the so-called ideal strength, sets the gold standard for the strength of a given …

Assessment of candidate materials for fusion power plants provide one of the major
structural materials challenges of the next decades. Computer simulation provides a useful …
