PESCI, Raphaël (2010)
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 ... -
Conférence invitée;PESCI, Raphaël (2015)
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 ...

Identification of Model Parameter for the Simulation of SMA Structures Using Full Field Measurements Conférence invitée;MERAGHNI, Fodil; ; ; ; (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad/ Wiley, 2015)
With the design of new devices with complex geometry and to take advantage of their large recoverable strains, shape memory alloys components (SMA) are increasingly subjected to multiaxial loadings. The development process ...

Conférence invitée; ;MERAGHNI, Fodil; ; (Trans Tech publications, 2013)
In this work, a method for the identification of the transformation surface of Shape Memory Alloys based on full field measurements is presented. An inverse method coupled with a gradient-based algorithm has been developed ...

Conférence invitée; ;MERAGHNI, Fodil; ; ; (Trans Tech Publications, 2013)
The thermomechanical behavior of Shape Memory Alloys (SMAs) is described by many micromechanical and phenomenological models. The first ones have material parameters whose physical meaning is based on the crystallography ...
