We study the mechanical properties of nanoglass (NG) nanopillars with diameters ranging from 4.5 to 54 nm by means of molecular dynamic simulations and compare the results with those obtained for nanopillars prepared from homogeneous glasses. NG nanopillars of two different types of glasses, namely, Cu₆₄Zr₃₆ and Pd₈₀Si₂₀, were cut from samples prepared by nanoparticle consolidation. The influence of nanopillar diameter on the deformation behavior and strain localization is investigated. Moreover, cyclic loading is used to explore the origin of stress overshoots in the stress–strain curves of NGs. Finally, from the calculated properties, a deformation map for NG and homogeneous glass nanopillars is derived.

我们通过分子动力学模拟研究了直径在4.5到54 nm之间的纳米玻璃（NG）纳米柱的力学性能，并将结果与​​由均质玻璃制备的纳米柱的结果进行了比较。从通过纳米颗粒固结制备的样品中切出了两种不同类型的玻璃的NG纳米柱，即Cu ₆₄ Zr ₃₆和Pd ₈₀ Si ₂₀。研究了纳米柱直径对变形行为和应变局部化的影响。此外，循环载荷被用于探索天然气的应力-应变曲线中应力超调的起源。最后，从计算出的特性中，得出了NG和均质玻璃纳米柱的变形图。
