However, an accurate 3D simulation is usually too time-consuming to be used in the early design stage. One solution is to use simplified Inverse or One Step approaches for the sheet forming modeling. Unfortunately, these methods often based on implicit static algorithms, suffer from convergence problems because of strong non-linearities. In this paper we firstly present several initial guess methods to speed up the convergence of the implicit static solver used in the Inverse Approach, then we present some new techniques for the treatment of vertical walls (balancing, opening, matrix condensing,) which has proven to be essential when dealing with complicated parts. All these improvements have been introduced into our in-house F.E. software REFORM and applied to the drawing of industrial automobile parts. The obtained rapid convergence enables the easy determination of various process parameters for the design of sheet forming process. It is concluded that a good initial solution and the treatment of vertical walls play an important role to speed up the Inverse Approach modeling of autobody stamping processes.Keywords:Deep DrawingInverse Approachinitial solutiongeometric mappingnon-linear resolution FiguresReferencesRelatedDetailsCited By 10Modeling and Optimization in Manufacturing by Hydroforming and StampingHakim Naceur and Waseem Arif27 April 2021Damage Prediction in Metal Forming Process Modeling and Optimization: Simplified ApproachesYing-Qiao Guo, Yuming Li, Boussad Abbès, Hakim Naceur and Ali Halouani4 September 2014A comprehensive blank development method for forming sheet metal partsJianjun Wu, Xin Wu, Liangcai Deng and Hakim Naceur13 December 2013 | The International Journal of Advanced Manufacturing Technology, Vol. 71, No. 5-8An initial solution estimation method based on As‐Rigid‐As‐Possible mesh parameterization for one‐step simulationQiaosheng Liu, Juntong Xi and Zhuoqi Wu29 Mar 2013 | Engineering Computations, Vol. 30, No. 3Damage Prediction in Metal Forming Process Modeling and Optimization: Simplified ApproachesYing-Qiao Guo, Yuming Li, Boussad Abbès, Hakim Naceur and Ali Halouani15 May 2014Analysis and design of hydroformed thin-walled tubes using enhanced one-step methodXavier Elie-dit-cosaque, Mohamed Said Chebbah, Hakim Naceur and Augustin Gakwaya2 August 2011 | The International Journal of Advanced Manufacturing Technology, Vol. 59, No. 5-8A membrane element model with bending modification for one step inverse methodJingxin Na, Jian Jiao, Yakun Yan and Haipeng Liu1 Jun 2011 | Acta Mechanica Solida Sinica, Vol. 24, No. 3An efficient spreading method for sheet metal parts based on outside normalWu Jian‐jun and Yang Han‐ping18 Jul 2008 | Engineering Computations, Vol. 25, No. 5Approche inverse améliorée pour la minimisation du retour élastique de pièces emboutiesSlim Ben-Elechi, Hakim Naceur, Catherine Knopf-Lenoir and Jean-Louis Batoz15 May 2012 | European Journal of Computational Mechanics, Vol. 17, No. 3Moving least squares response surface approximation: Formulation and metal forming applicationsPiotr Breitkopf, Hakim Naceur, Alain Rassineux and Pierre Villon1 Jun 2005 | Computers & Structures, Vol. 83, No. 17-18 Recommended Vol. 03, No. 04 Metrics History KeywordsDeep DrawingInverse Approachinitial solutiongeometric mappingnon-linear resolutionPDF download
