Implanté sur deux sites, le campus d’Angers et le pôle de réalité virtuelle de Laval, le LAMPA intervient dans les domaines de l’innovation, des procédés avancés de fabrication et de durabilité des matériaux et des structures. Le numérique et le virtuel sont au cœur des travaux de recherche, par exemple la simulation numérique du procédé pour la compréhension des phénomènes thermiques et mécaniques en jeu.

    LOUCA, Karim; ABDOLVAND, Hamidreza; ccMAREAU, Charles; MAJKUT, Marta; WRIGHT, Jonathan (Springer Science and Business Media LLC, 2021-01-13)
    The mechanical response of polycrystalline materials to an externally applied load and their in-service performance depend on the local load partitioning among the constituent crystals. In hexagonal close-packed polycrystals ...

    Virtual reality (VR) sketching tends to be democratized in the early stages of design for several reasons (e.g., improved creativity). Nevertheless, our field studies and the scientific literature identified some constraints ...

    Hot-forging is a process commonly used in the manufacturing of automobile parts such as connecting rods. Most hot-forged components are shot-blasted after forging in order to clean off the forging scale. The shotblasting ...

    One objective of this project is to propose a fatigue design approach that is able to account for a large range of machining surface defects and different component sizes and geometries. Due to the huge size difference ...
