Communication avec acte(2014)In order to face challenges of increased traffic and speed on their infrastructures, railway companies need to develop numerical tools able to predict the dynamic behaviour of the track. Currently, two approaches are widely ...

Communication avec acte(2015)Fatigue cracks in the contact wire are a possible cause of fracture which can induce huge costs. Fatigue study is thus of a great interest but requires an accurate computations of stress distributions. OSCAR is a SNCF ...

PESCI, Raphaël (Jacques Besson, Dominique Moinereau, Dirk Steglich, 2006)
A series of in-situ tensile tests was performed at various low temperatures to characterize the mechanical properties and the fracture processes of the 16MND5 steel: the damage was observed with a SEM and the internal ... -
Communication avec acte(2015)Catenary damping has long been a tuning parameter in pantograph-catenary dynamic interaction models. As the computed contact force is highly sensitive to the choice of damping model or coefficients, it became critical to ...

The predictions of the constitutive model agree with experimental results in terms of macroscopy stress-strain curves and volume fraction of martensite formed during loading

In this investigation, the thermo-viscoplastic behaviour of the steel AISI 304 has been examined. The experimental characterization of the material has been conducted in tension under wide ranges of strain rates.An analytical ...

Finally, the same in situ biaxial tensile tests were also performed with both SEM and XRD, first at low temperature in order to study the influence of temperature on the material behaviour and especially on martensite ...
