Tribological analysis of a sliding contact using finite element method – Complete Phd and Masters Thesis

[ad_1]

Introduction

Tribology is the study of friction, wear, and lubrication of interacting surfaces in relative motion. It plays a crucial role in various engineering applications, such as manufacturing, automotive, aerospace, and biomedical industries. Understanding the tribological behavior of sliding contacts is essential for improving the performance and reliability of mechanical systems. The use of finite element method (FEM) in analyzing tribological phenomena has gained significant attention due to its ability to provide detailed insights into the complex interactions between contacting surfaces.

This thesis focuses on the tribological analysis of a sliding contact using the finite element method. The study aims to investigate the effects of different operating conditions, surface properties, and lubrication regimes on the friction and wear behavior of the contacting surfaces. By utilizing FEM simulations, this research seeks to provide a comprehensive understanding of the underlying mechanisms governing the tribological performance of sliding contacts.
