In order to elucidate the mechanism of deformation and fracture microcomponents, numerical simulations are conducted for a nanoscopic wire film nickel without lattice defects on basis molecular dynamics using EAM(embedded atom method) potential. A bulk is also treated by applying periodic boundary condition comparison. These materials subjected tensile strain along the[001]direction fcc(face-centered cubic) lattice. Here, transverse stresses in material kept at zero during tension. The...
A morphological evolution of the growth Fe2B boride on steel substrate has been investigated using two dimensional (2D) multi-phase-field (MPF) simulations. In order to evaluate competitive between seeds during coating process, variations seed orientation have implemented. addition, in anisotropy boride, interfacial energy is considered evaluation phase-field evolution. It was observed that with structure 90° shows a preferential as compared at other orientations. On hand, different crystal...
As a series of studies that discuss the onset inelastic deformation based on atomic elastic stiffness (AES), we investigated AES in silicon by Tersoff interatomic potential. For comprehensive discussion including effect structural inhomogeneity surface and grain boundaries, performed tensile simulations bulk/nanowire Si single crystal, laminate bulk/bamboo nanowire with Σ5 twist boundary under very low temperature (T = 1 K). Not only stress–strain response, but also AESs at each atom point,...
In order to clarify the deformation behavior of bulk metallic glasses from atomistic viewpoint, an amorphous Ni-Al binary alloy is made and subjected tension by means molecular dynamics simulation. The initial equilibrium a melt-quench simulation single crystal in which Ni or Al atoms are randomly arranged on fcc lattice point. Both radial distribution Voronoi analysis attests that state. metal then with strain rate 1.0×109/s under periodic boundary condition, showing nonlinear stress-strain...
In order to clarify the physical meaning of eigenvector atomic elastic stiffness matrix, Bija=Δσia/Δεj, static calculations uniaxial tension are performed on various fcc, bcc, and hcp metals with four different embedded atom method (EAM) potentials. Many fcc show instability for constant volume mode, or (Δεxx, Δεyy, Δεzz) = (±1, ∓1, 0), under [001] tension. Bcc also loses resistance against other ±1, ∓2), in Hcp shows shear modes Δγyz Δγzx [0001] tension, which correspond migration by...
As a fundamental study on the adhesion of Ni-plating aluminum alloys, various molecular dynamics simulations are performed Ni/Al infinite laminate structure under tension, by changing mixing concentration Ni and Al at interface. The shows highest perfect (001) interface while it decreases with rate random in phases (10%, 30% 50% substitution each phase). Especially phase remarkably compare to same phase. (111) weaker than for interface, doesn’t largely affect reduction as interfaces always...
