REGAL Training Day
The REGAL Training Days (JFR), generally paired with the JER, offer complementary training to the student community. These trainings are technical in nature (inter-axis) or of general interest.
Training Day 2024
This year, the REGAL student community will be able to attend the first edition of the conference “Progrès en développement durable: la science et le génie au service de la transition écologique et énergétique”. This important event will provide an opportunity to learn about the results of applied research on aluminium from seven Quebec universities, companies and research centres, but also to become aware of the common issues and opportunities between different research fields. In addition to the scientific poster sessions, there will be more than 80 technical presentations on sustainable development in three days among the following themes:
• Process engineering, sustainable materials and renewable energies
• Green chemistry and bio-based products
• Resource management and valorization, circular economy
• Ecosystems, biodiversity, fight against and adaptation to climate change.
In addition, there will be five plenary presentations from recognized experts in sustainable development and three expert panels, including a panel organized by REGAL that will address issues specific to our research environment.

Artificial Intelligence in an Industrial Context 4.0: A Data Monster Training
Summary
With a range of sensors, it is generally wrongly believed that developing industrial projects based on data is easy… but behind each success, a team had to overcome difficulties that all companies wishing to implement these technologies will experience. During this presentation, Professor Gaudreault addresses the most common risks and pitfalls in this type of project.
Jonathan Gaudreault is a professor at Université Laval. He is the director of the “Consortium de recherche en génie des systèmes industriels 4.0”. His team creates decision-making systems based on artificial intelligence in collaboration with more than a dozen industrial partners such as APN, Produits forestiers Résolu, Biscuits Leclerc and CRIQ. Professor Gaudreault’s expertise has been recognized on numerous occasions; he is notably one of the recipients of the Canada Prize for Interdisciplinary Research in Science and Engineering.

Modelling the aluminium production process – approaches, strategies and examples
Summary
The aluminium production process is often difficult to model: it includes a wide range of interrelated physical phenomena (electrical, thermal, mechanical, electrochemical, magnetohydrodynamic, etc.) occurring in an industrial environment where measurements are limited and imperfect.
The objective of this training is to present some examples of modelling that have been successfully applied in industry. We will discuss a current distribution and ACD model, an algorithm for early detection of anodes placed at the wrong height, and a model representing CO2 bubbles under the anodes. Beyond the examples themselves, the emphasis will be on the best strategies for developing models that are useful in industry: Successfully representing the main physical phenomena, aiming for the right level of complexity, coupling different models to one another, and effectively exploiting all the currently available measuring tools.
Sébastien Guérard completed a bachelor’s degree in chemical engineering and a master’s degree in engineering at the Université du Québec à Chicoutimi in 2010. After his studies, he worked for a year at Hatch, where he specialized in CFD modelling. He then started working at Rio Tinto in 2011. His main areas of expertise
include the design of electrolysis cells, process optimization, and the improvement of control algorithms. This led him to develop several models related to the process, some using finite element or volume methods, others based on different types of mathematical, physical or statistical approaches. More recently, he has been involved in the design and operation of new measurements on electrolysis cells.

Planning and statistical analysis of experiments: The essential and efficient method for designing an experimental plan to understand and optimize a process in all areas of application
Summary of the Training
Engineers and scientists use experimentation as a fundamental strategy to increase their knowledge. The art and practice of experimental planning is not well known and is neglected by engineers and scientists. The basic concept for designing effective and efficient experimental plans for a multi-factor context is an extremely valuable tool for anyone who envisages a data collection and testing plan. There is confusion and erroneous recipes on the true method for planning experiments to guide the experimental phase of data collection in scientific research. The objective of our presentation is to propose the main concepts and safe rules to effectively guide any researcher in the construction phase of an experimental design for data collection during a scientific experiment. The proposed experimental designs and principles put forward will allow any researcher, in whatever the field of application, to obtain the maximum amount of information with the minimum of tests. The analysis of the results is done by proven statistical methods giving clear and unambiguous interpretations. When you test several factors at the same time, you get more results from your resources. The proposed experimental design strategies are flexible and can be used in the design of products and processes, in the laboratory and in production. They can also be used for the study and emulation of computer programs with heavy calculations. An experimental design in the field of aluminium will be used to illustrate the concepts.

Additive manufacturing of aluminium – Issues and potential
Training summary
Aluminium and its alloys have great potential in additive manufacturing, but they still have certain intrinsic constraints. The presentation will first cover the characteristics of aluminium alloys that dictate their use in additive manufacturing. The different AM processes will then be presented in relation to their ability to produce aluminium parts. The microstructural characteristics depending on the processes, the mechanical behaviour of alloys in AM and the aspects of non-destructive testing will also be covered.

Prediction of damage and fracture of extruded parts dedicated to collision applications
Training summary
The design of aluminium extrusions for collision structures, including bumpers, chassis and other structural components, depends on specific requirements such as the energy to be absorbed, the force transferred to the occupant and the available space. Currently there are challenges involved relating to the evaluation of the impact performance of a material, given the complex stress states and deformation paths. Determining the alloy temper and extrusion parameters is limited to experience. Regardless these choices must be regularly modified following extrusion tests in order to achieve the required ductility, often to the detriment of strength. This training demonstrates the development of a virtual tool to accurately predict the collision performance of a material and given extrusion parameters, upstream, at the design phase.
Jean-François Béland has been a research officer at the National Research Council for 14 years. He works on several cold and hot forming processes, specializing in numerical simulation techniques, such as finite elements and meshless methods, to study and optimize the forming, impact behaviour and assembly of aluminium.
