Au cours des dernières décennies, le développement de tôles d'acier avancé à haute résistance (AAHR), destinées de l'industrie automobile, a permis d'atteindre des niveaux supérieurs de de résistance tout en maintenant une ductilité adéquate, et ce, à faibles coûts de fabrication.Cependant, ces tôles d'aciers ont montré une tendance à basculer du mode de rupture ductile conventionnel, dominé

A turbulent two-vortex system at equilibrium, that is typical of aircraft wakes in the far field, is first obtained using large eddy simulation and is characterized: circulation distribution of the vortices; energy of the mean and fluctuating fields; energy dissipation rate associated with the turbulent equilibrium. A wall-resolved simulation of that system further interacting with the ground is

Advancements in the mechatronic design of bionic legs are increasingly driven by the need to create systems that seamlessly adapt to the complexities of real-world environments while supporting natural and intuitive interactions with users.

The urgent need to transition to cleaner energy sources is highlighted by record-breaking temperatures and increasingly frequent extreme weather. With fossil fuels currently meeting over two-thirds of global energy needs, developing fuel-flexible and environmentally friendly combustion technologies is essential.

Architectured materials, as defined by Ashby and Bréchet, are developed through a design process aimed at meeting specific requirements via functionality, behavior, or performance induced by a particular morphological arrangement of multiple phases.

Hexahedral meshes are used in engineering and computer graphics to describe complex geometric shapes by subdividing them into cube-like cells. Hexahedral meshes are widely considered advantageous over tetrahedral meshes, in terms of efficiency or their ability to align elements to relevant geometric features.

Laser Powder Bed Fusion (L-PBF) is the most widespread additive manufacturing method for aluminium alloys. There is a high demand for complex L-PBF parts in the aeronautic sector. Such parts could decrease aircraft weight and allow fuel savings and reduction of the environmental impact of air transportation.

Hydrogen is foreseen to be part of our future energy systems as Europe has the ambition to be a carbon-neutral continent by 2050.

During its re-entry into the atmosphere, the capsule withstands a strong shock due to its hypersonic velocity. This shock generates, near the Thermal Protection System (TPS), a lower velocity but extremely hot and reactive flow. As shown by previous space missions, there are still many uncertainties in the design of heat shields.

A rapidly expanding research area involves the development of routes to shape programmable three-dimensional (3D) structures with feature sizes in the mesoscopic range (that is, between tens of nanometres and hundreds of micrometres).
