Book Description
Due to its speed, low energy requirements, and the fact that it does not require a pre-drilled hole, the technique of self-piercing riveting (SPR) has been increasingly adopted by many industries as a high-speed mechanical fastening technique for the joining of sheet material components. Self-piercing riveting comprehensively reviews the process, equipment, and corrosion behaviour of self-piercing riveting, and also describes the process of evaluation and modelling of strength of self-piercing riveted joints, quality control methods and non-destructive testing.Part one provides an extensive overview of the properties of self-piercing riveting. Chapters in this section review the mechanical strength, fatigue, and corrosion behaviour of self-piercing riveted joints. The second part of the book outlines the processing and applications of SPRs, and describes the dynamic strength evaluation/crashworthiness of SPRs, and the modelling of strength of self-piercing riveted joints, before going on to discuss the assessment of the suitability of materials for self-piercing riveting. The concluding chapters describe the quality control and non-destructive testing of self-piercing riveted joints, optimization of the strength of self-piercing rivets, and provides an overview of self-piercing rivets in the automotive industry and the applications of self-piercing riveting in automated vehicle construction.Self-piercing riveting is a standard reference for engineers and designers in the aerospace, materials, welding, joining, automotive and white goods industries, as well as manufacturers of metal components for the automotive, aerospace, white goods and building industries. - Comprehensively reviews the process, equipment, and corrosion behaviour of self-piercing riveting - Describes the process of evaluation and modelling of strength of self-piercing riveted joints, quality control methods and non-destructive testing - Provides an overview of quality, optimization, applications and strength evaluations of self-piercing riveting

Book Description
Self-piercing riveting (SPR) has been employeed for the production of different subassemblies in the automotive industry since the early 1990s. A substantial amount of experimental work was traditionally required to find an appropriate combination of rivet and anvil design to satisfy the required joint parameters. The presented dissertation is describing the methodology of SPR design based upon numerical simulation and experimental methods of defining material properties, coefficients of friction for all interfaces, and fracture parameters in the SPR process. The further focus of this dissertation is to experimentally develop input parameters for the FEA model. The developed model is to be used as a tool during the SPR joint design and validation. Among required inputs are stress-strain curves validated for the range of strains taking place in the SPR process, as well as parameters for a fracture model for all involved materials using all sheets in the stack and the rivet material. In the current dissertation, the normalized Cockroft-Latham fracture criterion was employed for predicting fracture. Parameters of the fracture model for sheets were defined by a custom hole expansion test. The parameter for predicting fracture of the rivet was defined via expanding the tubular portion of the rivet in the heat-treated, i.e., as employed for the riveting condition. The multistep rolling-tensile testing procedure was used to define the flow curves of sheet materials. Lastly, the multistep cylinder compression test was employed to define the flow curve for the rivet material. Three different test processes were used to determine friction coefficients between the sheet materials in the stack and between the bottom sheet and the anvil. Those included 1) the comparison of the FEA model predicted and the experimentally validated joint cross-sections, 2) comparison of the FEA model predicted and experimentally validated rivet setting curves, and 3) comparison of the FEA predicted lap-shear tensile test strength to the experimentally validated lap-shear joint tensile strength. All modeling and tests were performed on the automotive industry representative sheet metal alloys and their respective thicknesses.

Book Description
The automotive industry requirements for vehicle weight reduction, weight containment, improved part functionality and passenger safety have resulted in the increased use of steel grades with a fully martensitic microstructure. These steel grades are essential to improve the anti-intrusion resistance of automotive body parts and the related passenger safety during car collisions. Standard advanced high strength steel (AHSS) grades are notoriously difficult to be formed by cold stamping; they are characterized by elastic springback, poor stretch flangeability and low hole expansion ratios. Hot stamping has therefore received much attention recently as an alternative technology to produce AHSS automotive parts.In this book, selected articles from the Fourth International Conference on Advanced High Strength Steel and Press Hardening held on August 20-22th, 2018 in Hefei, China, are compiled. It focuses on AHSS for the development of press hardening of high performance sheet metal for lightweight vehicle, advanced digital manufacturing technology, as well as the physical metallurgy principles of the hot stamping process.Aiming at the process design and industrial application for hot stamping of press hardened steel and high strength aluminium alloy sheet, the effect of temperature and strain rate on the formability and mechanical properties of the products is discussed. In addition, more practical cases are provided concerning accurate modelling and multi-physics coupling simulation of the hot stamping process. Furthermore, the influence of tool design on forming process, more precise process control strategies to increase production efficiency, and the improvement of hot stamping equipment by advanced design methods will also be presented.

Book Description
In the automotive industry, the need to reduce vehicle weight has given rise to extensive research efforts to develop aluminum and magnesium alloys for structural car body parts. In aerospace, the move toward composite airframe structures urged an increased use of formable titanium alloys. In steel research, there are ongoing efforts to design novel damage-controlled forming processes for a new generation of efficient and reliable lightweight steel components. All these materials, and more, constitute today’s research mission for lightweight structures. They provide a fertile materials science research field aiming to achieve a better understanding of the interplay between industrial processing, microstructure development, and the resulting material properties. The Handbook of Research on Advancements in the Processing, Characterization, and Application of Lightweight Materials provides the recent advancements in the lightweight mat materials processing, manufacturing, and characterization. This book identifies the need for modern tools and techniques for designing lightweight materials and addresses multidisciplinary approaches for applying their use. Covering topics such as numerical optimization, fatigue characterization, and process evaluation, this text is an essential resource for materials engineers, manufacturers, practitioners, engineers, academicians, chief research officers, researchers, students, and vice presidents of research in government, industry, and academia.

Book Description
Self-piercing riveting (SPR) is a high-speed method of joining sheet materials by creating a mechanical interlock between the sheets. Unlike conventional riveting, SPR does not require predrilling. Automobile industries adopted this joining technique because of its suitability in joining dissimilar materials and doing so at high-volume production. However, in SPR, the rivet plastically deforms and residual stress develops in the joint. The deformation behavior of the rivet and the residual stress distribution in SPR joints are poorly understood. This leads to difficulties in developing new product and optimizing the process. Development of new rivet and die geometries are also limited since the residual stress state in SPR joints are not fully described. Several key issues in modeling and measuring residual stress in SPR joints are discussed. How the plastically induced residual stress can be linked to the different phases of the riveting process is also described. This is an area of SPR with numerous prospects for research. It is expected that advancement will be achieved by a combination of techniques, including laboratory recreation, finite element modeling and manufacturing trials.
