A very stiff finitely extensible nonlinear elastic (FENE)-Fraenkel spring is proposed to replace the rigid rod in the bead-rod model. This allows the adoption of a fast predictor-corrector method so that large time steps can be taken in Brownian dynamics (BD) simulations without over- or understretching the stiff springs. In contrast to the simple bead-rod model, BD simulations with beads and F...

The welding process is an important component in many industrial operations. Welding input parameters play a very significant role determining the quality of weld joint. joint can be defined terms properties such as weld-bead geometry, mechanical properties, and distortion. Generally, all processes are used with aim obtaining welded desired parameters, excellent minimum So that this paper prese...

Cold metal transfer (CMT)–based wire-arc additive manufacturing (WAAM) is increasingly popular for the production of large and complex metallic components due to its high deposition rate, low heat input, excellent material efficiency. The accurate prediction bead geometry great importance enhance stability process dimensional accuracy. Besides wire feed speed (WFS) travel (TS), interlayer tempe...

The dynamics of fluid-borne superparamagnetic bead transport by field-driven domain walls (DWs) in submicrometer ferromagnetic tracks is studied experimentally together with numerical and analytical modeling. A combination of micromagnetic modeling and numerical calculation is used to determine the strength of bead-DW interaction for a range of track geometries and bead sizes. The maximum DW ve...
