Atomistic based continuum investigation of plastic deformation in nanocrystalline copper
A continuum model of nanocrystalline copper was developed based on results from independent atomistic calculations on 11 bicrystals containing high angle grain boundaries. The relationship between grain boundary structure and its mechanical response was investigated. Based on the atomistic calculations; a constitutive law for grain boundary interfaces was implemented within a finite element cal...
متن کاملMicrostructures and mechanical performance of polyelectrolyte/nanocrystalline TiO2 nanolayered composites
Biological materials with hierarchically laminated structures usually exhibit a good synergy between strength and fracture toughness. Here, we show that a bio-inspired (polyelectrolyte (PE)/TiO2)4 nanolayered composite with a thickness ratio of TiO2 and amorphous PE layers of about 1.1 has been prepared successfully on Si substrates by layer-by-layer self-assembly and chemical bath deposition m...
متن کاملEffect of Annealing Treatment on Mechanical Properties of Nanocrystalline α-iron: an Atomistic Study
Claims are often found in the literature that metallic materials can be nanocrystallized by severe plastic deformation (SPD). However, SPD does not generate a well-defined nanocrystalline (NC) material, which can be achieved by subsequent annealing/recovery treatment. In this study, molecular dynamics (MD) simulation is employed to study the effect of annealing on structure and mechanical prope...
متن کاملAtomistic Simulation of the Mechanical Behaviors of Cu/sic Nanocomposites
The nanocomposites containing nanosized microstructure have extensively motivated researchers to investigate the mechanical properties of such composites. Metal/ceramics nanocomposites, which are composed of low-melting-point metal and high-melting-point ceramics, can provide desirable mechanical properties including high specific stiffness, high plastic flow strength, creep resistance, good ox...
متن کاملAn investigation on Mechanical Properties of Apatite-Wollastonite-Diopside Glass-Ceramics Composites
Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...
