Dislocation climb models from atomistic scheme to dislocation dynamics
We develop a mesoscopic dislocation dynamics model for vacancy-assisted dislocation climb by upscalings from a stochastic model on the atomistic scale. Our models incorporate microscopic mechanisms of (i) bulk diffusion of vacancies, (ii) vacancy exchange dynamics between bulk and dislocation core, (iii) vacancy pipe diffusion along the dislocation core, and (iv) vacancy attachment-detachment k...
متن کاملDislocation Climb in the Electron Wind
When a current flows in a conductor, the electron wind can cause atoms to diffuse. This paper considers the consequences of such diffusion along dislocation cores. A dislocation climbing in a crystal is viewed as a non-equilibrium thermodynamic system to define the force that drives self-diffusion along the core. Not only is a dislocation a mass-transport pipe, it also climbs and generates more...
متن کاملAn Efficient High Order Method for Dislocation Climb in Two Dimensions
We present an efficient high order method for dislocation dynamics simulation of vacancy-assisted dislocation climb in two dimensions. The method is based on a second kind integral equation (SKIE) formulation that represents the vacancy concentration via the sum of double layer potentials and point sources located at each dislocation center, where the climb velocity of each dislocation (or the ...
متن کاملAn improved self-adaptive filter forecasting method
This paper improved the selfadaptive filter-forecasting model that is one of deterministic constant parameter forecasting models. An attenuation/gain function is drawn into a direct iteration search method that belongs to the multi-variables extreme value research based on the optimization theory, so that it combines the quantitative methods with the qualitative analysis by the experts and incr...
متن کاملAn Improved Method to an Impulsive and Delayed Discretized Model
In this paper, a discretized SIR model with pulse vaccination and time delay is proposed. We introduce two thresholds R* and R*, and further prove that the disease-free periodic solution is globally attractive if R* is less than unit and the disease can invade if R* is larger than unit. The numerical simulations not only illustrate the validity of our main results, but also exhibit bifurcation ...
