Mechanical properties of simple computer glasses

Edan Lerner

摘要:

计算玻璃物理学的最新进展使计算机玻璃的研究具有非常广泛的机械和动力学稳定性。然而,目前的文献缺乏一个全面的数据集,不同的计算机玻璃模型可以在同一基础上进行定量比较。在这里,我们提出了一个广泛的研究几个流行的计算机玻璃成型模型的机械性能。我们研究了表征玻璃弹性和弹塑性的各种无量纲数在不同条件下如何变化-在每个模型中和跨模型-目的是解开这些可观测量的模型参数,外部参数和简化协议依赖性。我们希望我们的数据集被用作解释工具,在未来的计算研究的弹性和弹塑性的玻璃固体。

英文摘要:

Recent advances in computational glass physics enable the study of computer glasses featuring a very wide range of mechanical and kinetic stabilities. The current literature, however, lacks a comprehensive data set against which different computer glass models can be quantitatively compared on the same footing. Here we present a broad study of the mechanical properties of several popular computer glass forming models. We examine how various dimensionless numbers that characterize the glasses' elasticity and elasto-plasticity vary under different conditions --- in each model and across models --- with the aim of disentangling the model-parameter-, external-parameter- and preparation-protocol-dependencies of these observables. We expect our data set to be used as an interpretive tool in future computational studies of elasticity and elasto-plasticity of glassy solids.
