A molecular dynamics-informed probabilistic cross-slip model in discrete dislocation dynamics

چکیده
We present here a quantitative study of dislocation cross-slip, an essential thermally activated process in deformation metals, discrete dynamics (DDD) simulations. implemented stress-dependent line-tension model DDD simulations, with minimal information from molecular (MD) This allows reproducing simulations the probabilistic cross-slip rate calculated MD for Cu large range stresses and temperatures. The implementation atomically-scale accurate simulating more accurately phenomena such as softening, dislocation-precipitate interaction patterning

Dislocation-precipitate Interaction in Discrete Dislocation Dynamics
This contribution deals with the numerical simulation of dislocation dynamics by means of parametric mean curvature flow. Dislocations are described as an evolving family of closed and open smooth curves driven by the normal velocity. The equation is solved using direct approach by semi-discrete scheme based on finite difference method. Numerical stability is improved by tangential redistributi...
متن کاملAtomistically informed dislocation dynamics in fee crystals
We develop a nodal dislocation dynamics (DD) model to simulate plastic processes in fee crystals. The model explicitly accounts for all slip systems and Burgers vectors observed in fee systems, including stacking faults and partial dislocations. We derive simple conservation rules that describe all partial dislocation interactions rigorously and allow us to model and quantify cross-slip process...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Coupling discrete dislocation dynamics with polycrystal plasticity
Lebensohn et al. [1] recently introduced an alternative description of crystal plasticity based on a fast-Fourier transform (FFT) algorithm. The FFT approach solves for the equilibrium stress and strains under the constraint of strain compatibility for systems with periodic microstructures. As currently developed, the FFT model describes plasticity with a set of elasto-viscoplastic constitutive...
