Aluminum alloys (AA) are widely used in automobile industry as lightweight materials attributed to the high strength to weight ratios and superior formability. Bending is a common and vital process in the sheet metal forming. Bendability is one of the most important formability characteristics in sheet metal forming, so it must be understood for robust aluminium stamping process designs. Crack and springback are major disadvantages in sheet metal forming. Many studies focused on the bending process using simulation and numerical methods, with experimental tests rarely being reported. A new edge bending methodology called "incremental bending" has been developed and implemented on aluminum sheet at room temperature. 3D digital image correlation, a non-contact, full field, optical measurement technique, was employed simultaneously to provide a high accuracy measurement of the full field strain distribution and springback curvature, making it very suitable for springback measurement. Using this method, peak bending strain was lowered, as well as a reduction of springback. Moreover, the risk of fracture is greatly lowered. The experimental results agree well with the theoretical analysis. This work could help to eliminate fracture, minimizes springback in sheel metal bending dramatically and improves formability and productivity, as well as provide a reference for researchers studying cold bending. The basic theory, system configurations, results analysis and applications are shown in detail in this dissertation.

Sheet metal bending is a common industry fabrication process. Outer surface crack is one of the major failure modes of aluminum sheet bending when the material is too thick or too brittle. This paper proposes a new multi-step incremental bending method to reduce the risk of bending failure. A novel laboratory test methodology is developed to test the 5xxx aluminum sheet bendability by using 3D digital image correlation (DIC) strain measurement system. A laboratory test apparatus with four different bending tool radii are designed/build. The test procedures for incremental bending test are also developed in this paper. Through the DIC image evaluation of a sequence deformation image and data processing, the major strain histories of the test samples are obtained. Strain comparison of the incremental bending with the conventional bending shows that the incremental bending can reduce peak strain on the outer surface. That is found that the more step and movement used, the more peak strain reduction will be. Based on the experimental results, potential applications of incremental bending are discussed.

Aluminium (Al) is a metal of great importance because of its excellent corrosion resistance, high electrical and thermal conductivity, good reflectivity, and very good recycling characteristics. The properties of heat-treatable Al-alloys can be further enhanced by the inclusion of a reinforcing phase that increases the mechanical properties of the overall composite. This book is a comprehensive guide on the different types of aluminum alloys and the new advances that have been made in developing and manufacturing aluminum alloys and composites. This text provides a comprehensive overview of the processing, formability, and chemical composition of aluminum alloys and composites. Part One is focused on evaluating the types and properties of advanced aluminum alloys and composites, while Part Two explores characterization. The advantage of this book is that it provides a detailed review of major advances that have occurred in the development and application of aluminum alloys and composites while outlining a development strategy for these materials.

Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis. Readers will find and in-depth look into various single- and multi-camera models (2D-DIC and 3D-DIC), two- and three-dimensional computer vision, and volumetric digital image correlation (VDIC). Fundamentals of accurate image matching are described, along with presentations of both new methods for quantitative error estimates in correlation-based motion measurements, and the effect of out-of-plane motion on 2D measurements. Thorough appendices offer descriptions of continuum mechanics formulations, methods for local surface strain estimation and non-linear optimization, as well as terminology in statistics and probability. With equal treatment of computer vision fundamentals and techniques for practical applications, this volume is both a reference for academic and industry-based researchers and engineers, as well as a valuable companion text for appropriate vision-based educational offerings.

Volume is indexed by Thomson Reuters CPCI-S (WoS).Collections of peer-reviewed papers are always excellent sources of knowledge and new ideas for researchers working in both universities and industry. The present collection, in particular, provides interdisciplinary and international resources; thus encouraging the close cooperation of materials scientists, and manufacturing and computer engineers and promoting the diffusion of research results, and technology transfer, in all areas of Sheet Metal Processing and Characterization. The main focus of this special volume is on innovation in forming processes, high-strength materials and joining technologies. The 72 papers are grouped into chapters on: Hydroforming, Joining , Manufacturing Systems, Micro Technologies, Quality/Surface Conditioning, Tooling, Stamping, Tube-Forming, Incremental Forming, Modelling, Materials and Testing, Drawing, Bending, and Roll-Forming.The volume offers important and interesting insights into R&D issues concerning Sheet Metal Processing: indeed, all SheMet Proceedings provide a state-of-the-art guide to this dramatically important industrial field. Discussing the latest trends in the metal forming, processing, and finishing industries, the proceedings of the April 2009 conference focuses on innovation in forming processes, high strength materials, and joining technologies. The 71 papers present recent research in hydroforming, joining, stamping, incremental forming, surface conditioning, modeling, material testing, drawing processes, and roll forming. The opening keynote speech investigates the forming potential of advanced high strength steels for structural car seat components. Other topics include enhanced formability of aluminum blanks by local heat treatment, melted polymer as a pressure medium in sheet metal forming, automating the design of cold roll forming tool sets, and preventing partial draw-in during high speed deep drawing.

Hydroforming uses a pressurised fluid to form component shapes. The process allows the manufacture of lighter, more complex shapes with increased strength at lower cost compared to more traditional techniques such as stamping, forging, casting or welding. As a result hydroformed components are increasingly being used in the aerospace, automotive and other industries. This authoritative book reviews the principles, applications and optimisation of this important process. After an introduction, the first part of the book reviews the principles of hydroforming, from equipment and materials to forming processes, design and modelling. The second part of the book reviews the range of hydroforming techniques, the shaping of particular components and the application of hydroforming in aerospace and automotive engineering. With its distinguished editor and team of contributors, Hydroforming for advanced manufacturing is a valuable reference for all those developing and applying this important process.
