Introduction

Welcome to our online course on Fracture Mechanics, a captivating exploration of the behaviour of materials when subjected to external forces that lead to cracking or breakage. This interdisciplinary field harmonises principles from mechanics, materials science, and applied mathematics to unravel the intricate mechanisms of crack growth and propagation in various materials and structures. The primary objective is to provide you with a comprehensive understanding of fracture mechanics parameters and their application in ensuring the safety and reliability of mechanical and structural components.

Throughout this course, you will delve into critical fracture mechanics parameters such as stress intensity factors, critical crack sizes, and fracture toughness. These parameters play a pivotal role in assessing the susceptibility of materials to cracking and determining the conditions under which cracks may propagate. Additionally, we will explore the significance of fatigue in fracture mechanics, acknowledging its paramount importance in evaluating the performance and reliability of mechanical and structural components. Fatigue, characterised by the progressive and localised structural damage that occurs when materials undergo cyclic loading, is a key consideration in designing components for extended operational lifespans.

Join us on this educational journey to gain insights into fracture mechanics parameters, understand the nuances of fatigue, and acquire the knowledge to engineer components that not only meet performance requirements but also exhibit enhanced reliability and durability in the face of real-world mechanical challenges.
