Metal Fatigue Testing and Analysis: Theory and Practice provides the theoretical knowledge and practical skills required to design durable metallic structures and components. The book thoroughly reviews fatigue and reliability theories for product durability designs, analyses, and validations, highlighting the latest advances and identifying key challenges. It is structured to guide readers in how to design targets from mission profile data, which is crucial in ensuring that structures (vehicle, systems, and components) meet the specific requirements of their applications. Insight is provided on how to analyze and design structures based on established targets, with practical insights and methodologies for structure designs provided.
Readers are guided through the development of validation tests to assess the durability of their designs, with emphasis placed on the importance of implementing reliability demonstration tests to ensure that test structures meet the design targets.
