Matrimony

Bridging the Scales from the Atomistic to the Continuum,For example, nanocrystalline materials processed by ball milling of powders or extensive shear deformation (e.g., equal channel angular extrusion [ECAE]) can have high defect densities, such as voids, and considerable lattice curvature. Accordingly, NC materials are often highly metastable and are s

Innovative Combinations of Atomistic and Continuum: Plastic Deformation of Nanocrystalline Materialchanism. For example, in the case of the emission of dislocation from grain boundaries, it is critical to predict the frequency at which a dislocation is emitted when a nanocrystalline (NC) sample is subjected to monotonic loading. Additionally, it is also necessary to know the effect of each emissi

Structure, Mechanical Properties, and Applications of Nanocrystalline Materials, an interphase region composed of grain boundaries and higher-order junctions (e.g., triple junctions, quadruple junctions). Early experiments on nanocrystalline materials have shown that the interphase region and particularly grain boundaries exhibit an almost grain size–independent thickness [1].

Bridging the Scales from the Atomistic to the Continuum, possible to accurately model or predict their deformation, fracture, and fatigue behavior as well as the relative tradeoffs of these responses with changes in microstructure. Even empirical models predicting deformation behavior do not exist due to lack of reliable data. Also, atomistic modeling ha
