An Efficient Numerical Model to Predict the Mechanical Response of a Railway Track in the Low-Frequency Range

With railway interoperability, new trains are allowed to move on the French railway network. These trains may present different designs from standard trains. This work aims to complete the current approach for vehicle admission on the railway…

A Reduced Model Based on Proper Generalized Decomposition for the Fast Analysis of IGBT Power Modules Lifetime

Abstract A reduced weakly-coupled thermo-mechanical model based on the proper generalized decomposition method was developed for the numerical analysis of power modules. The employed model reduction method enabled us to obtain, in a preliminary…

CONCRETE DRYING KINETICS: DEVELOPMENT OF AN ACCELERATED DRYING PROTOCOL IN FIRE TESTINGS

This work proposes an accelerated drying protocol that allows reaching a hydric and mechanical state representative of normal service conditions while optimizing the storage time of the specimen before the fire resistance test. The temperature and…

Experimental modeling of burnt oil shale impact towards ASR

The alkali-silica reaction (ASR) is a civil engineering issue that can be inhibited using supplementary cementitious materials such as burnt oil shale. Furthermore, these allow an improvement of the properties of the concrete as increasing density…

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…
