Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2007 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Increase in the complexity of the parts and emphasis on the low formability and expensive lightweight materials require the use of MultiPoint Cushion (MPC) systems in modern presses and optimal blank shapes to better control metal flow and increase drawability. Programming the MPC system for forming a part is difficult and costly to estimate by trial and error FE simulation and die tryouts as there are many variable to change. Hence, multipoint cushion system available in a modern press is hardly used in practice. Estimation of Blank Holder Force (BHF) for MPC could be best done through structured FE simulations in process design stage to realize MPC system potential. Successful application of FE simulations in stamping process design depends on the accuracy of the input parameters. Sheet material properties obtained from tensile test is insufficient for the FE analysis because maximum strain obtained in uniaxial tensile test is small compared to strains encountered in stamping operations. Therefore, there is a need for a test to determine sheet material properties over larger strain range for forming FE simulations. In this study, circular and elliptical bulge test was developed to estimate flow stress and anisotropy of sheet materials over strain range, nearly twice that of tensile test for use in process simulation. The material properties obtained from bulge test was found more appropriate for process simulation compared to tensile test. Numerical optimization technique coupled with FE analysis of the forming process was developed to predict optimum BHF required to program the multipoint cushion system. The developed technique was applied to predict the BHF to form a) GM liftgate-inner, b) IFU-Hishida part by stamping process, c) 90 mm diameter round cup by sheet hydroforming process with punch (SHF-P) and d) a rectangular part by sheet hydroforming with die (SHF-D). Predicted optimum BHF resulted in parts without failure and significantly reduced trial and error effort in the investigated stamping and sheet hydroforming operations. BHF variable in space/location significantly improved the formability/drawability compared to conventional method of BHF constant in space/location for the investigated parts in stamping and sheet hydroforming.

Available in PDF, EPUB and Kindle. Book excerpt: The present study aims to determine the optimum blank shape design for the deep drawing of arbitrary shaped cups with a uniform trimming allowance at the flange i.e. cups without ears. This earing defect is caused by planar anisotropy in the sheet and the friction between the blank and punch/die. In this research, a new method for optimum blank shape design using finite element analysis has been proposed. Explicit non-linear finite element (FE) code LSDYNA is used to simulate the deep drawing process. FE models are constructed incorporating the exact physical conditions of the process such as tooling design like die profile radius, punch corner radius, etc., material used, coefficient of friction, punch speed and blank holder force. The material used for the analysis is mild steel. A quantitative error metric called shape error is defined to measure the amount of earing and to compare the deformed shape and target shape set for each stage of the analysis. This error metric is then used to decide whether the blank needs to be modified or not. The cycle is repeated until the converged results are achieved. This iterative design process leads to optimal blank shape. In order to verify the proposed method, examples of square cup and cylindrical cup have been investigated. In every case converged results are achieved after a few iterations. So through the investigation the proposed systematic method of optimal blank design is found to be very effective in the deep drawing process and can be further applied to other stamping applications.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
