Adaptation et réduction de modèle dans les couplages local-global non-intrusifs : application à la conception robuste

This research work focuses on the so-called non-intrusive local-global model coupling procedure which has been proposed and widely analyzed and applied in structural mechanics during the last decade, and which constitutes a flexible and effective…

CLIPS OPERATION BETWEEN TYPE II AND TYPE III O(3)-SUBGROUPS WITH APPLICATION TO PIEZOELECTRICITY

Clips is a binary operation between conjugacy classes of closed subgroups of a compact group, which has been introduced to obtain the isotropy classes of a direct sum of representations E1 ⊕ E2, if the isotropy classes are known for each factor E1,…

Local-global DVC analyses confirm theoretical predictions for deformation and damage onset in torsion of pantographic metamaterial

Pantographs are a special class of metamaterials that do not obey theories of first gradient continua. In the present work, a pantographic metamaterial was printed and subjected to in situ torsion. The experiment was designed in order to investigate…

Experimental validation of the strut-and-tie design for reinforced concrete massive structures by deformation flow analysis

The design of reinforced concrete structures follows prescriptions of codes and standards (e.g., ACI and Eurocode). The strut-and-tie method is the only approach detailed in standards for the design of reinforcement of massive structures. Stut-and…

Développement d'un outil numérique pour la définition des conditions de circulation d'un matériel roulant sur la voie ferrée d'un point de vue de la fatigue du rail

In the context of railway interoperability, new trains are allowed to move on the french railway network and may have different designs from standard trains. Thus, it is important to complete the current approach for rolling stocks admission on the…

A real-time variational data assimilation method with hybrid modelling: Application to additive manufacturing

The online monitoring of the additive manufacturing process is a difficult task as the as- sociated physical phenomena are multiphysics and multiscale. The main difficulty comes from the numerical complexity which is associated to an expensive…

Drained and undrained heat capacity of swelling clays

In microporous materials, poromechanical drained (open pore) and undrained (close pore) conditions play a role in the thermo-mechanical properties, which can also be affected by specific ion effects. Heat capacity is a key property to understanding…
