Abstract

This paper analyzes the contact area of the contact between a deformable rough surface (smooth and rough) and a hard smooth sphere indenter using finite element method. A method was introduced to generate a three dimensional rough surfaces using Computer Aided Design (CAD) software. The rough surface model was developed based on the surface measurement data, while the smooth surface model was generated from the CAD software. Contact area and contact deformation were analyzed. Results showed that the contact area between rough surface versus sphere and smooth surface versus sphere is different.

Highlights

In micro scale, the real surface topography of mechanical component that has smooth appearing is rough surface
Machining process in component manufacturing will affect the surface quality, because the final process of machining is determined by surface roughness
Zhao et al (2005) created static contact model in elastic-plastic condition where asperity was modeled in sphere geometry

Summary

Introduction

The real surface topography of mechanical component that has smooth appearing is rough surface. Chang et al (2008) generated static contact model in elastic-plastic condition analytically where asperity was modeled in sphere geometry. Zhao et al (2005) created static contact model in elastic-plastic condition where asperity was modeled in sphere geometry.
