Fatigue and Fracture Mechanics: Damage Tolerance for Aerospace Systems

Structural failures in aerospace engineering often stem from overlooked material fatigue and crack propagation rather than simple lack of strength. To design safe modern aircraft and spacecraft, engineers must master the principles of durability and damage tolerance. This text-based course bridges the gap between theoretical solid mechanics and practical aerospace applications, ensuring you can predict and prevent catastrophic structural failures. You will begin by exploring the foundational history of fracture mechanics, fundamental stress intensity factors, and core materials science concepts before moving into advanced fatigue life estimation and modern inspection paradigms. Learn to apply industry-standard analytical methods to assess structural integrity under both monotonic and cyclic loading conditions. What you'll learn: Understand the foundational mechanics of crack initiation, propagation, and ultimate fracture in aerospace materials; Calculate stress intensity factors and energy release rates using linear elastic fracture mechanics; Evaluate high-cycle and low-cycle fatigue behaviors under complex cyclic loading profiles; Apply modern damage tolerance design philosophies and non-destructive evaluation (NDE) methodologies; Reference current ASTM testing standards for material characterization and crack growth tracking; Integrate modern computational analysis concepts and structural health monitoring trends into your design workflows. This course starts with essential definitions, historical failures, and basic solid mechanics to ensure all learners build a solid theoretical foundation. You will then progress through the mathematical formulations of fracture mechanics, fatigue life prediction models, and practical maintenance and inspection philosophies used in the aerospace industry today. This course is designed for aerospace engineers, structural designers, materials scientists, and technical managers looking to build a robust understanding of structural integrity. No advanced prior background in fracture mechanics is required, though a basic familiarity with undergraduate-level strength of materials is helpful.
