MINI SYMPOSIA

Description: In material 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, polymers and composites 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 material forming.

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.

Description: Nowadays, manufacturing processes are seeing a strong push towards the constant increase of their competitiveness and efficiency, together with more and more customization possibilities. Such improvements must also consider a higher level of sustainability and life cycle assessment, following the essence of a truly circular economy paradigm. Chain process involving forming and assembly technologies, as well as reliability assessment and control of the parts, must be considered for true and efficient optimization purposes. A unified or integrated analysis of the several aspects of manufacturing technologies can lead to a better understanding of the complex phenomena in forming, increasing its overall efficiency. Moreover, proper manufacturing process planning, as well as scrap minimization through near net shape manufacturing strategies, can lead to substantial energy and resource savings. Taking these broad aspects into consideration, the main goal of this Mini-Symposium is to provide a forum for discussion and presentation of research works, from both academia and industry stakeholders, focusing on integrated numerical and experimental methodologies that can provide viable paths to the sustainable forming processes and products of the future.

Description: The aim of this mini-symposium is to discuss the formability of metallic materials. Namely, their ability to undergo plastic deformation and result in products with minimum damage and defects. 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.
