NUMISHEET 2016: 10th International Conference and Workshop on Numerical Simulation of 3D Sheet Metal Forming Processes

The NUMISHEET conference series have been established as a world-class forum through which new intellectual ideas and technologies in the area of sheet metal forming simulation are exchanged. Previous NUMISHEET conferences have given enormous contributions to industry and academia in what regards the development of new methods and ideas for the numerical simulation of sheet metal forming processes. Previous NUMISHEET conferences were held in: Zurich (Switzerland, 1991), Isehara (Japan, 1993), Dearborn (USA, 1996), Besancon (France, 1999), Jeju Island (South Korea, 2002), Detroit (USA, 2005), Interlaken (Switzerland, 2008), Seoul (South Korea, 2011) and Melbourne (Australia, 2014). The NUMISHEET 2016 conference will be held in Bristol, UK. It features technical, keynote and plenary sessions and mini-symposiums in diverse sheet metal forming areas including the recently introduced incremental sheet forming and electromagnetic forming, as well as new prominent numerical methods such as IsoGeometric Analysis and meshless methods for sheet analysis. NUMISHEET 2016 will have eight academic plenary lectures delivered by worldwide recognised experts in the areas of sheet metal forming, material modelling and numerical methods in general. Also, NUMISHEET 2016 will have three industrial plenary lectures which will be addressed by three different companies with strong businesses in sheet metal forming processes: AutoForm, Crown Technology and Jaguar Land Rover. One of the most distinguishing features of NUMISHEET conference series is the industrial benchmark sessions, during which numerical simulations of industrial sheet formed parts are compared with experimental results from the industry. The benchmark sessions provide an extraordinary opportunity for networking, for the exchange of technologies related to sheet metal forming and for the numerical validation of sheet metal forming codes/software. Three benchmark studies have been organised in NUMISHEET 2016: BM1) "Benchmark 1 - Failure Prediction after Cup Drawing, Reverse Redrawing and Expansion", for both an aluminium AA 5352 and steel TH330 alloys, where the major objectives are predicting the earing profile of the cup and the failure point after complex nonlinear strain paths; BM2) "Benchmark 2 - Springback of a Jaguar Land Rover Aluminium Panel", where it is intended to study the thickness distribution and the springback profiles of a component of a Jaguar car at three particular cross-sections; BM3) "Benchmark 3 - Springback of an Al-Mg alloy in warm forming conditions", where the main objective is to predict the springback of a Al-Mg alloy after warm forming conditions. The conference proceedings will include a standard proceedings for regular and keynote papers (Part B) and a separated proceedings for the industrial benchmarks (Part A). Both proceedings will be published by the Institute of Physics (IOP) and will be included in SCOPUS database for a wide scientific dissemination. The benchmarks book proceedings, Part A, will be available through a printed paperback book and an electronic version and the proceedings book for the regular papers, part B, will be available through a USB pen drive. Both proceedings books will also be available online through the Institute of Physics publishers' platform. The NUMISHEET 2016 international conference is organising two special issues in two prestigious peer-reviewed international journals: 1) The International Journal of Solids and Structures; 2) The European Journal of Computational Mechanics. The NUMISHEET 2016 conference delegates are thus invited to submit an extended version of their papers for these two special issues, which will have a peer reviewed process as usual before publication in the journals.


PREFACE
The NUMISHEET conference series have been established as a world-class forum through which new intellectual ideas and technologies in the area of sheet metal forming simulation are exchanged. Previous NUMISHEET conferences have given enormous contributions to industry and academia in what regards the development of new methods and ideas for the numerical simulation of sheet metal forming processes. Previous NUMISHEET conferences were held in: Zurich (Switzerland, 1991), Isehara (Japan, 1993), Dearborn (USA, 1996), Besancon (France, 1999), Jeju Island (South Korea, 2002), Detroit (USA, 2005), Interlaken (Switzerland, 2008), Seoul (South Korea, 2011) and Melbourne (Australia, 2014.
The NUMISHEET 2016 conference will be held in Bristol, UK. It features technical, keynote and plenary sessions and mini-symposiums in diverse sheet metal forming areas including the recently introduced incremental sheet forming and electromagnetic forming, as well as new prominent numerical methods such as IsoGeometric Analysis and meshless methods for sheet analysis. NUMISHEET 2016 will have eight academic plenary lectures delivered by worldwide recognised experts in the areas of sheet metal forming, material modelling and numerical methods in general. Also, NUMISHEET 2016 will have three industrial plenary lectures which will be addressed by three different companies with strong businesses in sheet metal forming processes: AutoForm, Crown Technology and Jaguar Land Rover.
One of the most distinguishing features of NUMISHEET conference series is the industrial benchmark sessions, during which numerical simulations of industrial sheet formed parts are compared with experimental results from the industry. The benchmark sessions provide an extraordinary opportunity for networking, for the exchange of technologies related to sheet metal forming and for the numerical validation of sheet metal forming codes/software. Three benchmark studies have been organised in NUMISHEET 2016: BM1) "Benchmark 1 -Failure Prediction after Cup Drawing, Reverse Redrawing and Expansion", for both an aluminium AA 5352 and steel TH330 alloys, where the major objectives are predicting the earing profile of the cup and the failure point after complex nonlinear strain paths; BM2) "Benchmark 2 -Springback of a Jaguar Land Rover Aluminium Panel", where it is intended to study the thickness distribution and the springback profiles of a component of a Jaguar car at three particular cross-sections; BM3) "Benchmark 3 -Springback of an Al-Mg alloy in warm forming conditions", where the main objective is to predict the springback of a Al-Mg alloy after warm forming conditions.
The conference proceedings will include a standard proceedings for regular and keynote papers (Part B) and a separated proceedings for the industrial benchmarks (Part A). Both proceedings will be published by the Institute of Physics (IOP) and will be included in SCOPUS database for a wide scientific dissemination. The benchmarks book proceedings, Part A, will be available through a printed paperback book and an electronic version and the proceedings book for the regular papers, part B, will be available through a USB pen drive.

The NUMISHEET 2016 international conference is organising two special issues in two prestigious peer-reviewed international journals: 1) The International Journal of Solids and Structures; 2) The European Journal of Computational Mechanics. The NUMISHEET 2016 conference delegates are thus invited to submit an extended version of their papers for these two special issues, which will have a peer reviewed process as usual before publication in the journals.

ACKNOWLEDGEMENT
The NUMISHEET conference has a particular characteristic of joining experts from academia and industry for the discussion of numerical methods around the simulation of 3D sheet metal forming processes. The organising committee would like to express their gratitude to the many distinguished individualities that contributed enormously to the success of this conference. We gratefully acknowledge: The conference participants that are taking part in this prestigious conference either by presenting scientific papers or by participating with their simulations in the benchmark case studies; Professors The University of the West of England, Bristol, UK, for hosting this conference and for facilitating administrative resources such as contracting and administrative staff. In particular, we would like to thank Professor Glenn Lyons for his fantastic support to this conference; The sponsors of this conference: AutoForm (Gold Sponsor), ESI Group (Bronze Sponsor) and JSTAMP (Bronze Sponsor) for the financial support given;
