具有随机粗糙表面的弹性固体之间的界面分离:理论与数值方法的比较

Interfacial separation between elastic solids with randomly rough surfaces: comparison between theory and numerical techniques

A. Almqvist, C. Campana, N. Prodanov, B. N. J. Persson

摘要:

本文研究了具有随机粗糙表面的两弹性固体接触区的界面间距P(u)的分布。一个解析表达式推导出P(u),使用Escherson的接触力学理论,并比较使用(a)基于Boussinesq方程的半空间方法,(b)格林函数分子动力学技术和(c)智能块经典分子动力学获得的数值解。总的来说,我们发现所有不同的方法之间的良好协议。

英文摘要:

We study the distribution of interfacial separations P(u) at the contact region between two elastic solids with randomly rough surfaces. An analytical expression is derived for P(u) using Persson's theory of contact mechanics, and is compared to numerical solutions obtained using (a) a half-space method based on the Boussinesq equation, (b) a Green's function molecular dynamics technique and (c) smart-block classical molecular dynamics. Overall, we find good agreement between all the different approaches.
