Sheet Metal Forming Processes

Descripción del editor: "heet forming fundamentals are thoroughly addressed in this comprehensive reference for the practical and efficient use of sheet forming technologies. The principle variables of sheet forming-including the interactions between variables-are clearly explained, as a basic foundation for the most effective use of computer aided modeling in process and die design.Topics include stress analysis, formability criteria, tooling, and materials for sheet forming. The book also covers the latest developments in sheet metal forming technology, including servo-drive presses and their applications, and advanced cushion systems in mechanical and hydraulic presses."

The concept of virtual manufacturing has been developed in order to increase the industrial performances, being one of the most ef cient ways of reducing the m- ufacturing times and improving the quality of the products. Numerical simulation of metal forming processes, as a component of the virtual manufacturing process, has a very important contribution to the reduction of the lead time. The nite element method is currently the most widely used numerical procedure for s- ulating sheet metal forming processes. The accuracy of the simulation programs used in industry is in uenced by the constitutive models and the forming limit curves models incorporated in their structure. From the above discussion, we can distinguish a very strong connection between virtual manufacturing as a general concept, ?nite element method as a numerical analysis instrument and constitutive laws,aswellas forming limit curves as a speci city of the sheet metal forming processes. Consequently, the material modeling is strategic when models of reality have to be built. The book gives a synthetic presentation of the research performed in the eld of sheet metal forming simulation during more than 20 years by the members of three international teams: the Research Centre on Sheet Metal Forming—CERTETA (Technical University of Cluj-Napoca, Romania); AutoForm Company from Zürich, Switzerland and VOLVO automotive company from Sweden. The rst chapter presents an overview of different Finite Element (FE) formu- tions used for sheet metal forming simulation, now and in the past.

This book is a complete modern guide to sheet metal forming processes and die design - still the most commonly used methodology for the mass-production manufacture of aircraft, automobiles, and complex high-precision parts. It illsutrates several dfifferent approaches to theis intricate field by taking the reader through the 'hos' and 'whys' of product analysis, as well as the technqiues for blanking, punching, bending, deep drawing, stretching, material economy, strip design, movement of metal duting stamping, and tooling.

This practical and comprehensive reference gives the latest developments on the design of sheet forming operations, equipment, tooling, and process modeling. Individual chapters cover all major sheet forming processes such as blanking, bending, deep drawing, and more. Process modeling using finite element analysis is described in one chapter and discussed in all appropriate chapters. Other chapters cover sensors and die materials, which are critical for practical sheet forming applications. Other topics include relatively new technologies, such as warm forming of magnesium and aluminum alloys, forming of advanced high-strength steels (AHSS), and hot stamping. Chapters also address special sheet forming operations, like spinning, incremental forming, and mechanical joining, and processes related to sheet forming, such as sheet and tube hydroforming, roll forming, and high-velocity forming.

The numerical simulation of sheet metal forming processes has become an indispensable tool for the design of components and their forming processes. This role was attained due to the huge impact in reducing time to market and the cost of developing new components in industries ranging from automotive to packing, as well as enabling an improved understanding of the deformation mechanisms and their interaction with process parameters. Despite being a consolidated tool, its potential for application continues to be discovered with the continuous need to simulate more complex processes, including the integration of the various processes involved in the production of a sheet metal component and the analysis of in-service behavior. The quest for more robust and sustainable processes has also changed its deterministic character into stochastic to be able to consider the scatter in mechanical properties induced by previous manufacturing processes. Faced with these challenges, this Special Issue presents scientific advances in the development of numerical tools that improve the prediction results for conventional forming process, enable the development of new forming processes, or contribute to the integration of several manufacturing processes, highlighting the growing multidisciplinary characteristic of this field.
