The mechanisms of dislocation intersection and strain hardening in fcc crystals are
examined with emphasis on the process of junction formation and destruction. Large-scale …

Abstract The Quasicontinuum (QC) Method, originally conceived and developed by Tadmor,
Ortiz and Phillips [1] in 1996, has since seen a great deal of development and application by …

A three-dimensional discrete dislocation dynamics plasticity model is presented. The
approach allows realistic boundary conditions on the specimen, as both stress and …

The main objective of this paper is to develop a multiscale method for the analysis of carbon
nanotube systems. The multiscale coupled governing equations are first derived based on a …

We develop a nodal dislocation dynamics (DD) model to simulate plastic processes in fcc
crystals. The model explicitly accounts for all slip systems and Burgers vectors observed in …

This work gives an overview of the theoretical background and of the numerical modelling
framework used to describe the mechanical properties and the response of materials on …
