This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the HI-VEL project is to establish the feasibility of high velocity forming methods and to quantify the enhancement achievable with these techniques in the formability of high strength steel (HSS) and stainless steel sheets and tubes for automotive applications. Electromagnetic forming (EMF) and electrohydraulic forming (EHF) processes were studied during the HI-VEL project. After a first mechanical characterisation at strain rates up to 1000s-1, the following materials were selected for the high velocity experimental testing: AISI441 (1.4509), HT800XD (DP800), Dogal800DPX (DPX800), HT700TD (TRIP700) and IF210. The materials constitutive data at high strain rates were obtained for the Johnson Cook material modelling. EMF and EHF simulations were validated with experimental high velocity tests. The fatigue behaviour of high velocity formed samples was similar to the conventionally formed ones. Due to the low electrical conductivity of the HSS and stainless steels, the EMF technology showed its viability for these materials only in the case of small forming grades applications, such as the electromagnetic sizing of U-parts in order to eliminate the elastic recovery. For any other deep drawing operation, EMF technology can be applied to steels using an electrical conductive driver that accelerates the steel part towards the die. Comparing the conventional bulge forming and the multi-impulse EHF, the obtained dome heights increased from 57 to 70 mm for TRIP700 steel and from 48.5 to 54 mm for DPX800 steel. Multi-impulse EHF increased the formability of HSS and has interesting industrial applications, such as forming undercut part designs using a split die.

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.

This book was released on 2012-07-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 15 years, the application of innovative steel concepts in the automotive industry has increased steadily. Numerical simulation technology of hot forming of high-strength steel allows engineers to modify the formability of hot forming steel metals and to optimize die design schemes. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming focuses on hot and cold forming theories, numerical methods, relative simulation and experiment techniques for high-strength steel forming and die design in the automobile industry. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming introduces the general theories of cold forming, then expands upon advanced hot forming theories and simulation methods, including: the forming process, constitutive equations, hot boundary constraint treatment, and hot forming equipment and experiments. Various calculation methods of cold and hot forming, based on the authors’ experience in commercial CAE software for sheet metal forming, are provided, as well as a discussion of key issues, such as hot formability with quenching process, die design and cooling channel design in die, and formability experiments. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming will enable readers to develop an advanced knowledge of hot forming, as well as to apply hot forming theories, calculation methods and key techniques to direct their die design. It is therefore a useful reference for students and researchers, as well as automotive engineers.

Available in PDF, EPUB and Kindle. Book excerpt: The automotive industry plays a determinant role in the economy of developed countries. Sheet metal forming is one of the most important processes in car manufacturing. Recent trends in car production may be characterized by the application of lightweight principles. Its main priority is to fulfill both the customers,Äô demands and the increased legal requirements. The application of high strength steels may be regarded as one of the potential possibilities. Applying high strength steels has a positive response for many of the requirements: increasing the strength may lead to the application of thinner sheets resulting in significant mass reduction. Mass reduction is leading to lower consumption with increased environment protection. However, increasing the strength can often lead to the decrease of formability, which is very unfavorable for the forming processes. In this chapter, an overview of recent material developments in the automotive industry concerning the use of new-generation high strength steels will be given. In this paper, the material developments are emphasized from the point of view sheet metal forming; therefore, our focus is on the body-in-white manufacturing in the automotive industry.

Book excerpt: Briefly reviews the basic principles of metal forming but major emphasis is on the latest developments in the design of metal-forming operations and tooling. Discusses the position of metal forming in manufacturing and considers a metal-forming process as a system consisting of several interacting variables. Includes an overall review and classification of all metal-forming processes. The fundamentals of plastic deformation - metal flow, flow stress of metals and yield criteria - are discussed, as are significant practical variables of metal- forming processes such as friction, temperatures and forming machines and their characteristics. Examines approximate methods of analyzing simple forming operations, then looks at massive forming processes such as closed-die forging, hot extrusion, cold forging/ extrusion, rolling and drawing (discussion includes the prediction of stresses and load in each process and applications of computer-aided techniques). Recent developments in metal-forming technology, including CAD/CAM for die design and manufacture, are discussed, and a review of the latest trends in metal flow analysis and simulations.
