Fatigue in Additive Manufactured Metals starts by providing a brief overview of the fundamental mechanics involved in metal fatigue and fracture, then looks at the unique properties of additive manufactured metals, before diving into an in-depth exploration of how and why fatigue occurs in additive manufactured metals, solutions for preventing it, best-practice design methods, and more. It recommends cutting-edge evidence-based approaches for designing longer lasting additive manufactured metals, discusses the latest trends in the field and the various aspects of low cycle fatigue, and looks at both post-treatment and manufacturing process-based solutions. It covers new attempts in providing international standards and testing procedures of additive manufactured metal parts, discusses the environmental impacts of additive manufacturing of metals, and outlines simulation and modeling scenarios.
- Discusses the underlying mechanisms controlling the fatigue behavior of additive manufactured metal components as well as how to improve the fatigue life of these components via both manufacturing processes and post-processing
- Studies the variability of properties in additive manufactured metals, the effects of different process conditions on mechanical reliability, probabilistic versus deterministic aspects, and more
- Outlines nondestructive failure analysis techniques and highlights the effects of unique microstructural characteristics on fatigue in additive manufactured metals
