Modeling the brittle–ductile transition in ferritic steels. Part II: analysis of scatter in fracture toughness
A dislocation simulation model has been proposed to predict the brittle–ductile transition in ferritic steels in Part I. Here we extend the model to address the problem of inherent scatter in fracture toughnes...

Modeling the brittle–ductile transition in ferritic steels: dislocation simulations
We present a model for the brittle–ductile transition in ferritic steels based on two dimensional discrete dislocation simulations of crack-tip plasticity. The sum of elastic fields of the crack and the emitte...

Dislocation simulation of brittle-ductile transition in ferritic steels
Two-dimensional discrete dislocation simulations of the crack-tip plasticity of a macrocrack-micro-crack system representing the fracture behavior in ferritic steels are presented. The crack-tip plastic zones ...

Theory and experiment of nanostructure self-organization in irradiated materials
Irradiation of materials by energetic particles (e.g., electrons, ions and neutrons) is associated with very high internal power dissipation, which can drive the underlying nano- and microstructure far from no...

Modeling laser-induced deformation patterns: Nonlinear effects and numerical analysis
The formation of laser-induced deformation patterns on thin films and surfaces may be described by a dynamical model for the coupled evolution of defect densities and deformation fields of the material. Increa...

Green's function for the elastic field of an edge dislocation in a finite orthotropic medium
A fundamental solution of plane elasticity in a finite domain is developed in this paper. A closed-form Green's function for the elastic field of an edge dislocation of arbitrary Burger's vector at an arbitrar...

On the Growth and Form of Dislocation Patterns
Defects are known to play an important role in the macroscopic behavior of equilibrium and non equilibrium structures. They are able to disorganize spatio-temporal patterns, to trigger transitions between patt...

Spatial Instabilities and Defect Ordering in Solids
Spatial instabilities leading to the formation of defect patterns and microstructures seem to appear generically in solids driven away from thermal equilibrium by physicochemical constraints. Some of these ins...

Numerical Simulation 0f Dislocation Patterns during Plastic Deformation
A new method for the numerical simulation of dislocation patterns in solids undergoing plastic deformation is introduced. The term dislocation dynamics (DD) is used to describe the technique and to distinguish...

Modeling the early stages of thin film formation by energetic atom deposition
The early stages of thin film formation are described by a simple hybrid model that couples a set of discrete kinetic rate equations to a Fokker-Planck (FP)-type continuum. Unique features of the atomic proces...

Fusion neutron test facility requirements for interactive effects in structural and high-heat-flux components
A relevant design data base is needed for structural components in near-term and commercial fusion devices. A high-flux, high-fluence fusion neutron test facility is required for testing the failure mechanisms...
