In this Article, I review the development of computer simulation techniques for studying
radiation effects in materials from 1946 until 2018. These developments were often closely …

This review examines the size effects observed in the mechanical strength of thin metal films
and small samples such as single-crystalline pillars, whiskers, and wires. Experimental …

A method for solving small-strain plasticity problems with plastic flow represented by the
collective motion of a large number of discrete dislocations is presented. The dislocations …

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …

New perspectives on the phase field approach in modeling deformation and fracture at the
fundamental defect level are reviewed. When applied at sub-angstrom length scales the …

The viscoplastic deformation (creep) of crystalline materials under constant stress involves
the motion of a large number of interacting dislocations. Analytical methods and …

The first Phase Field model of evolution of a multi-dislocation system in elastically
anisotropic crystal under applied stress is formulated. The model is a modification and …

A thermodynamics-based variational method is developed to establish the equations of
motion for three-dimensional (3D) interacting dislocation loops. The approach is appropriate …

Dislocation velocities and mobilities are studied using molecular dynamics simulations for
edge and screw dislocations in pure aluminium and nickel, and edge dislocations in Al …

Dynamic strain ageing (DSA) is the phenomenon in which solute atoms diffuse around
dislocations and retard dislocation motion, leading to negative strain-rate sensitivity (nSRS) …
