Materials Science: Fracture and Fatigue Analysis for Engineering

Understanding how and why materials fail is critical to preventing catastrophic engineering disasters. This text-based course introduces you to the core principles of fracture mechanics and fatigue life prediction, equipping you with the analytical tools to evaluate structural integrity. You will learn to assess how different materials—ranging from metals and polymers to modern composites and thin films—behave under stress and environmental degradation. By working through clear explanations and structured engineering problems, you will develop the skills to predict when a component might fail and how to design against crack propagation. You will transition from learning foundational stress-intensity factors to applying modern fatigue models in real-world scenarios. What you'll learn: - Understand foundational concepts of linear elastic and elastic-plastic fracture mechanics. - Analyze microstructural toughening mechanisms across metals, ceramics, and composite materials. - Calculate stress-intensity factors and predict crack growth rates under cyclic loading. - Apply stress-life and strain-life approaches to estimate fatigue life in engineering components. - Evaluate the impact of environmental factors, including corrosion fatigue and creep fracture. - Examine modern interface fracture mechanics and failure prevention in microelectronics and bioimplants. The course begins with foundational definitions of stress concentration, fracture toughness, and basic loading modes. You will then progress through detailed written analyses of fatigue crack propagation models, variable amplitude loading, and real-world failure analysis case studies. This course is designed for engineering students, junior structural engineers, and materials science enthusiasts who want to build a solid foundation in failure analysis. No advanced background in fracture mechanics is required, though a basic understanding of strength of materials is helpful.
