PESCI, Raphaël; BECKER, Eric; LANGLOIS, Laurent; BIGOT, Regis (Trans Tech publications, 2015)
After analazing,the microstructure of the thixoforged parts, some mechanisms of material flow are proposed. -
Conférence invitée; ; ;MERAGHNI, Fodil (2016)
In this work, a new 3D thermomechanically coupled phenomenological model is proposed for SMAs. SMA behavior is described through several strain mechanisms, each associated with its proper internal variables. Forward and ...

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 ...

Conférence invitée;MERAGHNI, Fodil; ; (2016)
The presented experimental work describes the nondestructive examination of polymer based composites using an acoustic method under the consideration of nonlinear effects. The technique is based on the fact that material ...

Conférence invitée; ; ; ; ;PESCI, Raphaël (2011)
This work presents a constitutive model for metastable austenitic steels exhibiting Strain Induced Martensitic Transformation (SIMT). Based on the description of the kinetics of phase transformation proposed by Olson and ...

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; ;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 ...
