The Handbook of Flexible and Smart Sheet Forming Techniques presents a collection of research on state-of-art techniques developed specifically for flexible and smart sheet forming, with a focus on using analytical strategies and computational, simulation, and AI approaches to develop innovative sheet forming techniques. Bringing together various engineering perspectives, the book emphasizes how these manufacturing techniques intersect with Industry 4.0 technologies for applications in the mechanical, automobile, industrial, aerospace, and medical industries. The first section of the book introduces the concepts, classifications, variants, process cycles, and materials for flexible and smart sheet forming techniques and compares them with other conventional sheet forming processes. Subsequent sections delve deeper into topics such as: hardware and software required for these techniques; parameters, responses, and optimization strategies; the mechanics of flexible and smart sheet forming; simulation approaches; applications; and future innovations and directions. Each chapter will feature research outcomes, illustrations, case studies, and examples useful to anyone who needs to better understand and utilize these new manufacturing technologies.
