Minisymposia

(Minisymposia coordinators are bolded(italic))

MS1 Formability of metallic materials
Prof. D. Banabic(Technical University of Cluj Napoca, Romania), Prof. F. Barlat (Pohang University of Science and Technology, Republic of Korea), Prof. T. Kuwabara (Tokyo University of Agriculture and Technology, Japan), Dr. A. Ofenheimer (Virtual Vehicle, Graz, Austria), Dr. Holger Aretz (HYDRO, Germany), Dr. T. Balan (ENSAM Metz, France)

The mini-symposium “Formability of metallic materials” is aimed as a broad discussion forum for the most up-to-date theoretical, numerical and experimental approaches addressing the formability of metallic materials. All metallic materials are considered, and most particularly new structural materials with lightweight potential associating high strength and crashworthiness to a reduced weight of the parts. Contributions are expected on the development and onset of necking and strain localization, as well as other phenomena that limit the formability, including the impact of constitutive models specific to these new materials such as anisotropy, complex strain-path hardening, damage, strain-rate sensitivity, etc., described at different scales. Moreover, the effect of material / experimental scatter has become a serious issue for the robust application of formability predictions in an industrial context. All forming processes can be considered without exception, in particular new forming processes and approaches, including (but not restricted to) incremental forming, hot/warm forming, micro-forming, etc.

MS2 Forging and rolling

Prof. B.-A. Behrens (Leibniz Universität Hannover, Germany), Prof. M. Merklein (FAU Erlangen-Nürnberg, Germany), Prof. P. Peura (Tampere University of Tech, Finland), Ass. Prof. Cecilia Poletti (Graz University of Technology)

This mini-symposium should provide a forum for discussion and dissemination of the latest scientific findings and technology advances related to material production and processing by rolling and forging. The topics covered by the mini-symposium include, but are not limited to: characterisation and modelling of flow; damage and fracture behaviour of new workpiece and tool materials as well as friction and heat transfer phenomena; new approaches to numerical modelling of process-related material flow and failure; experimental and numerical process design and optimisation; computer-aided process control. More general issues, related to the cost and energy process efficiency, will be addressed as well. Contributions of both academia and industry are welcome.

MS3 Composites forming processes

Prof. P. Boisse (INSA Lyon France), Prof. R. Akkerman (University of Twente, The Netherlands), Prof. F. Chinesta (Ècole Centrale Nantes, France), Prof. S. Lomov (Katholieke Universiteit Leuven, Belgium), Prof. J. Sherwood (University of Massachusetts Lowell, USA)

The use of composite materials is expanding rapidly in various fields, in particular in civil aeronautics. The centre wing box of A380 is made from composite materials; the new aircrafts of Boeing and Airbus have composite wings and a composite fuselage. These composite materials become a major issue in order to decrease the mass and the fuel consumption of the aircraft. These high level applications of composite materials created a significant demand for scientific knowledge and computational tools of composite materials. The mechanical behaviour of the composite materials in service is dominated by the fibre orientation and density. The forming process, in turn, determines the fibre distribution. Hence, not only the in service performance (stiffness, damage, fatigue…) has to be predicted, but certainly also the complex manufacturing processes, of which there are many. Their knowledge and their modelling are essential for the analysis of the composite structures in service. Since 2001 and the Liege ESAFORM conference, an annual “Composite forming processes” mini symposium gathers researchers from Europe, and also from USA, Asia and Australia, who can present their works and exchange their points of view concerning research in the field of composite forming (twenty to forty communications each year). Conference ESAFORM thus became a privileged and single place for this subject. Experimental and numerical "benchmarks" were set up on in-plane shear properties, double dome forming and friction. They are discussed within the composites forming mini-symposia. The topics of the developed sessions concern in particular: Material characterization; Constitutive laws during forming; Forming simulations; Mesoscopic analyses; Resin injection; Thermoforming; Contact and friction; Benchmark efforts.

MS4 Friction and wear in material processing

Prof. L. Dubar (Université de Valenciennes, France), Dr. A.Ghiotti (Università degli Studi di Padova, Italy), Prof. A. Dubois (Université de Valenciennes, France), Prof. M. Dubar (Université de Valenciennes, France), prof. V-M. Kuokkala (Tampere University of Tech, Finland)

Friction, lubrication and wear are all important issues in materials processing, dictating boundary conditions of the mechanical problems as well as productivity via tool life. This justifies constant efforts, both experimental and theoretical, to understand, predict and control. All aspects of tribology in materials processing will be addressed in this mini-symposium: (i) Processes from the molten state to finishing, including metal cutting and metal forming, polymer or ceramic processing, surface finishing and surface engineering; (ii) Applications are called not only in materials processing, but also in other fields of mechanical engineering, to foster exchanges of different practices; (iii) Experimental measurement, in situ as well as ex-situ, predictive multiscale or phenomenological modeling, or consequences of friction on process mechanics, tool life and product quality; (iv) Coatings, surface treatments and new approaches to decrease friction and protect against wear and seizure while respecting increasingly severe environmental rules (Minimum Quantity Lubrication, new lubricants and additives including “greener” ones, applications of tool/workpiece coatings…)

MS5 Multiscale & continuum constitutive modelling

Prof. A. M. Habraken (University of Liège, Belgium), Prof. F. Chinesta (Ècole Centrale Nantes, France), Prof. L. Tabourot (Polytech Annecy-Chambéry, France), Prof. R. J. Alves de Sousa (University of Aveiro, Portugal), Prof. R. Wagoner (The Ohio State University, U.S.A.)

The goal of this mini-symposium is to share ideas about constitutive modeling for any material (metals like AL, steel, Ti, Mg.. but also glass, wood, food, textile, composite…) that can be formed. The studied scale goes from atomistic to macroscopic one. If your model scale prevents to perform a forming process but allows identifying a higher scale model able to do it, or if it helps to understand if the formed material will have the required properties, it is welcome. Your work must just show the link with the final goal of material forming. Multiscale models involving numerical homogenization schemes are appreciated however looking at a single scale is of course a first step. So models such as macroscopic phenomenological models or crystal plasticity constitutive laws are also welcome. The symposium welcomes experimental contributions allowing identification and validation of the models, or strategies for identification. Variability of material's properties is a critical factor that that can deeply affects process. Therefore material properties have to be measured as often as necessary. Regarding identification, strategies that allow on-line identification are encouraged. In order to increase productivity, nowadays material are submitted to more and more extreme production conditions to obtain more rapidly more complex geometries. Models have therefore to be more and more versatile. Contributions to models that covers: complex loading paths; high strain rates, high temperatures, cyclic loading would be appreciated. Contributions may focus on any aspect of the material response that contributes to its formability (hardening, rate sensitivity, anisotropy, toughness, phase transformation). The coupling between thermal, mechanical and metallurgical behavior is another key factor for material forming.

Non-conventional processes

Prof. J. Partinen (Aalto University, Finland), PhD J. Tuomi (Aalto University, Finland)
Additive manufacturing

The mini-symposium of non-conventional processes aims to facilitate the exchanges of the scientific information concerning the so-called non-conventional processes. In accordance with an accepted convention, one can consider that the non-conventional processes are based essentially on increasing the energy available in the working zone, by different ways, so that either a traditional machining process develops under better conditions, or the machining process develops on new principles, fundamentally different in comparison with the basic principle of the traditional machining processes (the principle of the plastic deformation). One can also appreciate that the non-conventional machining processes uses a non-traditional mechanism of interaction between the tool and the workpiece or non-traditional media are used in order to achieve the transfer of energy from the tool to the workpiece. The last decades proved an increased interest for highlighting new aspects of the non-conventional processes, for improving the performances specific to these processes, for identification of new applications of the non-conventional processes. The group of non-conventional machining processes includes the machining processes that use electrical discharges or other physical effects of the electric current, the electrochemical machining processes, the chemical machining processes, the plasma and ion beam machining processes, the ultrasonic machining processes, the laser beam machining processes, the electron beam machining processes, the machining processes with moving fluids, the machining processes that use magnetic field, the hybrid machining processes etc. The topics of the minisymposium concern the machining processes that use the electrical discharges or other physical effects of the electric current, the electrochemical machining processes, the ultrasonic machining processes, the beam machining processes, the machining processes that use moving fluids or magnetic field, the hybrid machining processes, the explosive, magnetic-pulse, peen, and other forming processes, the non-conventional processes of micro-forming, the numerical simulations and modelling of non-conventional processes, the performance evaluation of non-conventional processes, the non-conventional methods and tests for material characterization etc.

Additive manufacturing is technology in which different parts or shapes are made by adding thin layers of material one above the other, where each layer is a cross section of the final shape. This technology has been used in different industries for about 20 years. Improvements in the quality of the output from layer addition based machines have meant that currently, there is a much closer link to the final product than it used to be in the very beginnings of this technology. Nowadays functional commercialised parts are manufactured by an additive technique in many industries.The Additive manufacturing part of mini-symposium aims to gather innovative solutions for AM-technologies and applications. Especially processes and methods to achieve final products not models.

The goal of the minisymposium is to examine revolutionary structures, materials, design techniques, manufacturing techniques, and methods of analysis for products and processes. It will emphasize processes and products manufactured by forming processes which have the potential for improving environmental sustainability through reduced life cycle energy consumption. These benefits may arise from novel techniques for weight reduction or new manufacturing methods which require less energy compared to existing manufacturing techniques in forming. The main topics of the minisymposium are: (i) new strategies in light weight design, including new life-cycle concepts in metal forming (e.g. reuse, recycling); (ii) new methodologies of designing lightweight products manufactured by forming processes; (iii) computational methods for the simulation of processes related to the main topics of this minisymposium; (iv) energy efficiency in the existing supply chain for metal forming and (v) new forming processes for lightweight products.

Dr. V. Sobotka (Université de Nantes, France), Dr. K. Mocellin (CEMEF, MINES ParisTech, France), Dr. T. Pättikangas (VTT, Finland)

Heat transfer is inherent in a large number of forming processes in the fields of metals, polymers, composites, ceramics, glass, etc. Heat effects strongly impacts on the thermomechanical properties of the produced parts. Thus, to reach the criteria of quality, performance, durability and the requirements of production rates, they must be accurately modelled and controlled not only in the material but also in the tools. The aim of this symposium is thus to bring together scientists dealing with modelling and experimental analysis of heat transfer applied to material forming processes. We will welcome contributions dealing with analysis of applications for which heat transfer plays an essential part. The main topics of the minisymposium are: characterization and modelling of thermophysical properties in homogeneous and heterogeneous media; characterization and modelling of coupled heat transfer in forming processes; thermal metrology; phase change problems; heat treatments; heat transfer phenomena in moulds/tools: conductive heat transfer, infrared heating, induction heating of metals, etc.; heat transfer phenomena in welding processes.

The present symposium aims to present the most recent developments in the field of numerical simulation of processes and advanced material models, in a large variety of processes and materials, ranging from the classical stamping and forging technologies through most advanced processes such as incremental sheet forming, hydroforming and electro-magnetic forming, among others For material modeling, contributions are expected not only focusing on metallic materials, but also advanced materials like composites or coated-materials. The increasing need for complex parts production using advanced materials relies strongly on the development of advanced and cost effective numerical simulation techniques, to provide reliable and cost effective solutions to the product designer. This can only be achieved with elaborated and well grounded formulations on finite element technology and/or multiscale methods, large deformation and large strain formulations, anisotropic material models (either phenomenological and dislocation/texture based), proper algorithmic contact and friction treatment and advanced geometric description of tools. In this sense, the present symposium intends to be a contribution in achieving better solutions for realistic forming problems, trying to establish a bridge between academic and industrial major researchers and end-users, and foreseeing lines of development in the near future.
