Full Description
This open access book compiles the groundbreaking research conducted by the Collaborative Research Center (CRC) 871, centered around the "Regeneration of Complex Capital Goods." This comprehensive work unveils an array of innovative methods developed through CRC 871, designed to revitalize and enhance the functional attributes of these critical assets. From non-destructive characterization of heavily stressed turbine components to the dynamic behavior of regenerated structural elements, each chapter offers a meticulous exploration of diverse facets in the field. The book also addresses the crucial consideration of variability in repair processes and material properties, as well as the comprehensive control of regeneration processes. With insights into simulation-based process design, fast measurement techniques, and resilience-based decision criteria, this volume provides a comprehensive view of the cutting-edge approaches employed. Moreover, readers will find a detailed process chain for condition-based regeneration, offering a practical framework for implementation. Finally, the book sheds light on the importance of targeted public relations in disseminating the invaluable research carried out by Collaborative Research Center 871. This extensive compilation not only showcases the scientific rigor behind maintaining complex capital goods but also demonstrates the collaborative efforts that brought together experts from various fields to push the boundaries of regeneration technology.
