Les alliages d’aluminium à haute résistance, comme le 7075, sont reconnus pour leurs propriétés mécaniques élevées et présentent un fort intérêt pour les applications aéronautiques et spatiales, où le compromis masse/résistance est critique. La fabrication additive offre à cet égard des perspectives majeures en termes de liberté de conception, d’optimisation des structures et d’économie de ma

Hydrogen is a key energy carrier for a sustainable future, with applications in transport, storage, and industry. However, its safe use is challenged by hydrogen embrittlement, a phenomenon in which hydrogen diffuses into metals and reduces their strength and ductility, potentially leading to sudden failure.

This thesis investigates earthquake ground motion in Belgium, with the objective of improving seismic hazard assessment in a low-to-moderate seismicity region.

PhD Defense: An experimental and numerical investigation of CO2 diluted, oxy-fuel combustion in a reciprocating engine using mixtures of natural gas and hydrogen by Mauro DAESE (TFL)Decarbonizing internal combustion engines (ICEs) remains a significant challenge in the global effort to mitigate greenhouse gas emissions.

With the ongoing climate crisis, it is key to re-design the energetic sector, as well as the hard-to-abate industries. In such tasks, it is important to consider the role of reacting flows for industrial applications.

The increasing demand for lightweight, high-performance structural components in aerospace, defence and energy sectors has intensified interest in aluminium alloys produced by additive manufacturing.

Carbon accounting enables an organization to quantify its emissions, identify its main hotspots, and comply with evolving climate regulations, while also reducing costs and climate-related risks. By building on this diagnosis to design its own climate action plan, the company can prioritise the most effective measures, engage employees and partners, and demonstrate credible progress.

This work investigates plastic deformation heterogeneity at the macroscopic and microscopic scales within metallic alloys.

Ejectors are passive devices for mixing, compression, or vacuum generation, widely used in aeronautics, refrigeration, and process industry. They operate by expanding a high-pressure primary flow to entrain a lower-pressure secondary flow, reaching an intermediate pressure after mixing.
