Crystalline structure and grain boundary identification in nanocrystalline aluminum using K-means clustering
Amigo, Nicolás [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Matemat Fis & Estadist, Chile] (IOP Publishing Ltd., 2020-09)K-means clustering was carried out to identify the atomic structure of nanocrystalline aluminum. For this purpose, per-atom physical quantities were calculated bymeans ofmolecular dynamics simulations, such as the potential ... -
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
Amigo, Nicolás [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Matemat Fis & Estadist, Chile]; Urbina, Felipe [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile] (Elsevier, 2020-11)The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ...
