MS01: Composites forming processes

Coordinator: Prof. Philippe Boisse

Co-Organizers: Prof. Akkerman, Dr Emmanuelle Abisset-Chavanne , Prof. Lomov, Prof. Sherwood

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 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. 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; Permeability, Fiber suspensions, Thermoforming; Contact and friction; Benchmark efforts.

MS05: Integrated manufacturing and sustainability

Coordinator: Prof. Robertt Angelo Fontes Valente

Co-Organizers: Prof. Pierpaolo Carlone, Prof. Sandrine Thuillier, Prof. Ricardo Sousa, Dr. Giuseppe Ingarao, Prof. Joost Duflou, Prof. Sami Chatti

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.

MS13: Semi-solid processes

Coordinator: Prof. Ahmed Rassili

Co-Organizers: Dr. Naher, Prof. Brabazon

Description: Semi-solid metal processing (SSM) is a near net shape variant of metal forming. The process is used with all metallic alloys and widely applied to non-ferrous metals, such as aluminium and magnesium, steel application remain at laboratry scale. The process combines the advantages of casting and forging. The process is also named thixoforming, due to the fluid property thixotropy, which is the phenomenon that allows this process to work. Simply, thixotropic fluids shear when the material flows, but thicken when standing. The potential for this type of process was first discovered in 1970s. There are four different SSM processes: thixoforging, thixocasting, rheocasting, thixomolding…The industrial development of thixoforming must be accompanied by knowledge and control of the various parameters driving the process: the identification of the suitable materials for thixoforming; the homogeneous temperature heating of the slug before deformation; design or re-design of the part to adapt it to the process; the forming parameters including ram speed and load profiles, hold time and pressure at the end of the stroke, die temperature, die material. The handling system is also important; it allows the slug to be transferred, in the semi-solid state, between the heating zone and the tooling and to eject the thixoformed part so as to ensure the quality heat treatment of the part. In parallel to experimental investigations, modelling and simulation of die fill and rheological property measurement remain one of the challenging investigations to predict most of these parameters. Bringing semi-solid forming community together with experts in numerical simulation and material forming will allow sharing great experiences in the field of advanced metal processing.
