Abstract

Usually, contact mechanics focus on semi-infinite solids, so that any interaction between normal and in-plane deformation is commonly disregarded. However, when dealing with layers of finite thickness, this assumption is no longer valid, and the specific geometry of the contact pair plays a key role in determining the normal-tangential coupling. In this study, we focus on the exemplar case of a thin deformable layer in frictional sliding contact with a rough profile, where the interplay between tangential friction and normal pressure may lead to significantly different contact behavior compared to the uncoupled case, both in terms of contact area size and frictional response.

面内应力对薄层摩擦行为的影响

通常，接触力学关注的是半无限固体，因此通常忽略法向变形和平面内变形之间的任何相互作用。然而，当处理有限厚度的层时，这种假设不再有效，接触对的特定几何形状在确定法向切向耦合方面起着关键作用。在这项研究中，我们重点研究了薄可变形层与粗糙轮廓摩擦滑动接触的示例情况，在接触面积大小和摩擦响应方面，切向摩擦和法向压力之间的相互作用可能导致与非耦合情况相比显著不同的接触行为。

期刊介绍： Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
