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; ;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 ...
