IMSIA. Institute of Mechanical Sciences and Industrial Application UME. Mechanical Engineering Department A joint research unit CEA, CNRS, EDF, ENSTA Paris, Institut Polytechnique de Paris, 91120 Palaiseau, France. IMSIA (Institute of Mechanical Sciences and Industrial Applications) and UME (ENSTA Paris Mechanical Engineering Department) deals with the mechanics of industrial structures for applications in low-carbon energy and Defence sectors, in order to address major challenges with CEA, EDF and DGA. > Read more about IMSIA > Read more about IMSIA > Read more about UME > Read more about UME Research areas Durability and Sustainability of materials and structures Fluid Dynamics and Solid Mechanics Fluid Structure Interactions Smart materials and multiphysics couplings Aero-vibro-acoustics Industrial Software Development Key figures 43 Permanent researchers 13 Post-doctoral researchers 32 PhD students 50 Average number of publications per year MECHANICS discover UME labos > discover UME labos > discover IMSIA website > discover IMSIA website > The main research topics at IMSIA are: • Durability and safety of structures (fatigue, fracture and wear of industrial components); • Additive manufacturing and its application to repair; • Fluid dynamics and two-phase transients; • Structural vibrations and wave propagation for mechanics. IMSIA participates to the development of flexible, robust and efficient numerical simulation software: Cast3M, EUROPLEXUS, Code_Aster and Code_Saturne developed by the members. The research activities of UME are characterized by a strong multi disciplinary interaction between several branches of solid and fluid mechanics. smart material (shape memory alloys, metamaterials, electroactive polymers, magnetic, piezoelectric), fluid dynamics and aerodynamics, acoustic analyses for complex systems, usually nonlinear, with interactions as fluid-structure interaction, vibroacoustic, aero-elasticity and aeroacoustics and mechanics for health. They cover theoretical foundations and industrial applications, modelling and numerical simulation.
