The energetics and length scales associated with the interaction between point defects (vacancies self-interstitial atoms) grain boundaries in bcc Fe was explored. Molecular statics simulations were used to generate a boundary structure database that contained $\ensuremath{\approx}$170 varying tilt twist character. Then, vacancy atom formation energies calculated at all potential sites within 15 \AA{} of boundary. present results provide detailed information about vacancies atoms symmetric...
A set of modified embedded-atom method (MEAM) potentials for the interactions between Al, Si, Mg, Cu, and Fe was developed from a combination each element's MEAM potential in order to study metal alloying. Previously published parameters single elements have been improved better agreement generalized stacking fault energy (GSFE) curves when compared with ab initio generated GSFE curves. The element pairs were constructed based on structural elastic properties NaCl reference structure...
For very shallow indentations in W, Al, Au, and Fe-3wt%Si single crystals, hardness decreased with increasing depth irrespective of or decreasing strain gradients. As such, gradient theory appears insufficient to explain the indentation size effect (ISE) at depths less than several hundred nanometers. Present research links ISE a ratio between energy newly created surface plastic dissipation. Also, contact volume was nearly constant for range depths. Based on above, an analytical model...
In this article, a study is performed on the accuracy of radial basis functions (RBFs) in creating global metamodels for both low- and high-order nonlinear responses. The response surface methodology (RSM), which typically uses linear or quadratic polynomials, inappropriate models highly RBF, other hand, has been shown to be accurate responses when sample size large. However, most complex engineering applications only limited numbers samples can afforded; it desirable know whether RBF...
We experimentally studied beaks of the red-bellied woodpecker to elucidate hierarchical multiscale structure–property relationships. At macroscale, beak comprises three structural layers: an outer rhamphotheca layer (keratin sheath), a middle foam and inner bony layer. The area fraction each changes along length giving rise varying constitutive behaviour similar functionally graded materials. microscale, keratin scales that are placed in overlapping pattern; has porous structure; big centre...
Structural, elastic, and thermal properties of cementite (${\mathrm{Fe}}_{3}C$) were studied using a modified embedded atom method (MEAM) potential for iron-carbon (Fe-C) alloys. Previously developed Fe C single-element potentials used to develop Fe-C alloy MEAM potential, statistics-based optimization scheme reproduce structural elastic cementite, the interstitial energies in bcc Fe, heat formation alloys L${}_{12}$ B${}_{1}$ structures. The stability was investigated by molecular dynamics...
