论文摘要
使用相关随机矩阵理论研究了强烈无序宿主材料的局部弹性特性。界面区域显示刚度的显着增加,厚度取决于疾病的强度。结果表明,这种作用在纳米复合材料中起着至关重要的作用,其中每个纳米颗粒周围形成界面区域。研究的界面效应可以显着增加纳米颗粒对纳米复合材料宏观刚度的影响。界面区域的厚度由异质性长度尺度确定,并且与玻色子峰的长度尺度相同。
The local elastic properties of strongly disordered host material are investigated using the theory of correlated random matrices. A significant increase in stiffness is shown in the interfacial region, which thickness depends on the strength of disorder. It is shown that this effect plays a crucial role in nanocomposites, in which interfacial regions are formed around each nanoparticle. The studied interfacial effect can significantly increase the influence of nanoparticles on the macroscopic stiffness of nanocomposites. The obtained thickness of the interfacial region is determined by the heterogeneity length scale and is of the same order as the length scale of the boson peak.
