Mini-symposia
MS01: ADDITIVE MANUFACTURING
MS Coordinator: Dermot Brabazon dermot.brabazon@dcu.ie
MS Co-organizer: Antonello Astarita, Christian Grandfils, Sumsun Naher, Anne Mertens
Description: The aim of this min-symposium is to discuss the optimisation, capabilities and development within Additive Manufacturing. The pre-process, in-situ process, and post process aspects of additive manufacturing are important to characterise and understand well how these impact on the final produced part properties. Experimental, fundamental modelling and data analytic developments in relation to additive manufacturing are considered within this mini-symposium. Charactreisation of aspects of additive manufacturing production quality will be discussed within this mini-symposium.
MS02: COMPOSITES FORMING PROCESSES
MS Coordinator: Pierpaolo Carlone pcarlone@unisa.it
MS Co-organizer: Luise Kärger, James A. Sherwood, Philippe Boisse, Stepan Lomov
Description: The use of composite materials is expanding rapidly in various fields, in particular in civil aeronautics. These high level applications of composite materials created a significant demand for scientific knowledge and computational tools for composite material manufacturing. The mechanical behavior of the composite materials in service is dominated by the fiber orientation and density. The forming process, in turn, determines the fiber 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. Since2001 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. The ESAFORM conference 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; Permeability, Fiber suspensions, Thermoforming; Contact and friction; Benchmark efforts, Natural fibres as reinforcement, Additive manufacturing of composites.

Limiting mechanisms are not restricted to plastic flow localization, fracture and spring back, which are only a few examples under consideration. Contributions based on experimental, theoretical and numerical approaches and leading to a better understanding of the relationship between material properties, mechanical and thermal loading, and other environmental constraints on the formability of metallic materials are encouraged
MS06: FRICTION AND WEAR IN METAL FORMING
MS Coordinator: Javad Hazrati j.hazratimarangalou@utwente.nl
MS Co-Organizer: Lander Galdos, Chris Valentin Nielsen
Description: In metal forming, relative motion of the tool and workpiece during production makes friction and wear phenomena (tribology) of the utmost importance. On that account, accurate prediction of friction and wear is necessary for designing zero-defect manufacturing processes. The tribological performance in forming processes is influenced by several parameters at the micro- and macro levels (local contact conditions: surface texture, contact pressure, temperature and lubrication). Thus, for optimum process design, improving formability, enhancing tool life and finally control of tribology, a better understanding of tribology and an accurate prediction of friction/wear in forming processes are necessary. In this mini-symposium, different aspects of tribology in cold/hot forming of (sheet/bulk) metals will be discussed. The topics that will be covered in this mini-symposium in particular are: modeling friction and wear; tribological characterization methods; surface engineering and control of friction/wear in cold/hot forming processes.

MS15: SUSTAINABILITY ON MATERIAL FORMING
MS Coordinators: Giuseppe Ingarao giuseppe.ingarao@unipa.it
MS Co-Organizer: Rosa Di Lorenzo, Daniel Cooper
Description: Reducing anthropogenic environmental impact is an urgent issue to deal with. Technological innovation is needed in all the economic sectors in order to replace current practices with environmentally friendly alternatives. Scientists have to make a research effort to decouple the economic growth from the resource consumption. Reducing the environmental impact of Manufacturing and more in general putting in place the strategies of the Circular Economy (CE) paradigm are some of the most important targets to deal with. Manufacturing scientists have to tackle such challenge, they are called to innovate the manufacturing processes as well as to find new manufacturing processes suitable for End-of-Life components reuse. The symposium will be a platform for stimulating the scientific debate about environmental sustainability of forming processes. The mini-symposium welcomes papers dealing with both the environmental impact analysis of forming processes as well as their role as CE enablers.
Energy and resource efficiency of forming processes, LCA analyses of formed component/products, forming as eco-friendly materials processing, forming processes as Recycling/Remanufacturing/ Reuses strategies, Industrial Symbiosis practices involving forming processes, are some of the topics that will be discussed within the mini-symposium.
MS16: PROPERTY-CONTROLLED FORMING
MS Coordinators: Markus Bambach mbambach@ethz.ch, Wolfram Volk wolfram.volk@utg.de
Description: The production of reliable metallic high-performance components in many areas. Up to now, however, forming processes are predominantly open-loop controlled processes with regard to the product properties, i.e. in the forming process there is no measurement of the property-determining microstructure and no feedback to the control variables of the process. Numerous disadvantages are associated with this. If forming processes cannot adjust to disturbances in the process and fluctuations in the workpiece properties, long development phases for new materials and products, time-consuming post-processing and the production of scrap may be the consequence. In view of the ever increasing pressure towards resource efficient and sustainable materials processing, forming processes are needed in which the product shape and properties are both set within specified tolerances despite unavoidable fluctuations. This mini-symposium welcomes articles that aim at promoting forming processes towards closed-loop control of product properties. Submissions from metal forming technology, process simulation, sensor systems, control architectures and hardware and material engineering related to the goal are welcome.
