Abstract: Hot stamping is a relatively new and upcoming technology in the automotive industry used for the manufacturing of lightweight crash resistant parts with ultra high strength. The Finite Element (FE) simulation of hot stamping has to consider the combined effects of thermal, mechanical and microstructural fields. As a result, simulation of hot stamping is a complex process and requires detailed information on various factors such as material properties, process parameters and the right choice of software code. This report presents a complete list of all the important material properties and process parameters required for FE simulation of hot stamping. A sample part geometry was obtained from an industrial partner of the Center for Precision Forming at The Ohio State University and FE simulations of the part were carried out using the FE code DEFORM. The modeling and results of these simulations are presented in this report. Based on the results, a new methodology has been proposed that makes use of two different FE codes namely, DEFORM and PAM-STAMP in order to combine the advantages of the two in simulating hot stamping processes.

Hot stamping is a hot drawing process which takes advantage of the polymorphic steel behavior to produce parts with a good strength-to-weight ratio. For the simulation of the hot stamping process, a nonlinear two-scale thermomechanical model is suggested and implemented into the FE tool ABAQUS. Phase transformation and transformation induced plasticity effects are taken into account. The simulation results regarding the final shape and residual stresses are compared to experimental findings.

This book summarizes the advanced manufacturing technology of original innovations in hot stamping of lightweight car body. A detailed description of the technical system and basic knowledge of sheet metal forming is given, which helps readers quickly understand the relevant knowledge in the field. Emphasis has been placed on the independently developed hot stamping process and equipment, which help describe the theoretical and experimental research on key problems involving stress field, thermal field and phase transformation field in hot stamping process. Also, a description of the formability at elevated temperature and the numerical simulation algorithms for high strength steel hot stamping is given in combination with the experiments. Finally, the book presents some application cases of hot stamping technology such as the lightweight car body design using hot stamping components and gradient hardness components, and the cooling design of the stamping tool. This book is intended for researchers, engineers and graduate students in vehicle engineering, mechanical engineering, especially in the field of advanced manufacturing technology. The book also provides a useful reference for other new technology related temperature and phase transformation, such as aluminum-magnesium alloy hot stamping.

Abstract: The simulation of hot stamping is rather complex and challenging, and requires information about properties of die and sheet materials, heat transfer, and friction between the deforming material and the dies. A large number of researchers use different commercial codes, such as LS-Dyna, Pamstamp, Autoform, and DEFORM to conduct hot stamping simulations with various levels of success. In this study DEFORM, a commercial code widely used for the analysis of hot, cold and warm forging operations and die design has been used. This code can consider elastic and plastic deformations of the sheet material, friction, heat transfer and elastic deflections of the dies. Two part geometries have been analyzed, using information provided in the literature as well as that obtained from various companies that produce hot stamped parts. The results indicate that it is possible to predict the deformation and temperatures in the part and in the dies by considering the variation of interface heat transfer in function of interface pressure. Using this approach it is also possible to optimize the design of cooling channels in the dies. It appears that the approach, used in this study, is quite promising for use in industrial environment to optimize die and process design for hot stamping.

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.

A single-crystal plasticity model as well as a gradient crystal plasticity model are used to describe the creep behavior of directionally solidi?ed NiAl based eutectic alloys. To consider the transition from theoretical to bulk strength, a hardening model was introduced to describe the strength of the reinforcing phases. Moreover, to account for microstructural changes due to material ?ux, a coupled diffusional-mechanical simulation model was introduced.
