Creation of High-Strength Structures and Joints (PDF)

Volume is indexed by Thomson Reuters BCI (WoS).This work presents the results of the initial stage of research of some sub-projects of the Collaborative Research Centre SFB 675, "e;Creation of High-Strength Structures and Joints by Setting up Local Material Properties"e;, set up in 2006 by the German Research Foundation (DFG). This Collaborative Research Centre is the result of cooperation between the research institutes of Clausthal University of Technology and Leibniz Universitat, Hanover. The purpose of SFB 675 is to develop materials and manufacturing processes for high-strength structures, having graduated and locally engineered properties, by exploiting material, physical and/or geometrical effects. The incorporation of locally altered material properties, tailored to handle the strains expected to be encountered during use, lead to increases in the efficiency of the whole structure. This book offers an interesting overview of this intriguing topic.A second volume presents more results from a research project of the same name that began in 2006 in Germany. It sought to develop materials and manufacturing processes for high strength structures with gradually and locally engineered properties, by exploiting material-physical and/or geometric effects. Among the topics are using the aging effect to change the local properties of structure components, laser bead-on-plate welding and overlap seams for increasing the strength and rigidity of high strength steel, developing combined manufacturing technologies for high-strength structural components, fatigue life calculations concepts for structures with locally modified properties, and acoustic measurements to proof high-strength structures and joints.
