The Technology Transfer group of École des Mines operates at the crossroads between research and industrial reality. Formed by PhD-level mechanical engineers specialized in numerical modeling and simulation, the group works in synergy with researchers at Ecole des Mines, acting as an assistance service for PhD students and researchers, and places its long-standing expertise gained there at the service of industry. New functionalities are then developed in the Z-set code to satisfy specific industrial needs. Sophisticated and high-performance on-demand calculations can be performed for the industrial partners. Finally, the team organizes courses to train end-users in the optimized use of the vast range of possibilities of Z-set.
Onera, the French Aerospace Lab, is a multidisciplinary organization that brings together experts in energetics, aerodynamics, materials, structures, electromagnetism, optics, instrumentation, atmosphere and space environments, complex and onboard systems, information processing and long-term design.
The materials and structure branch has a long-standing reputation in the field of constitutive models and damage mechanics. This is applied in several domains, such as high-temperature metallic or composite materials and structures for aerospace engines, as well as their damage tolerance. In order to develop and test new models, Onera has contributed very significantly to the development of the finite element code Z-set and, in doing so, has acquired a strong experience in FE formulations and implementations. We bring in our expertise with finite elements and material mechanics, and massively parallel high-performance computations.
