International audience; 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 revers

International audience; A transformation criterion that includes the effect of tension-compression asymmetry and texture-induced anisotropy is used to describe the size of the transformation region surrounding the tip of an edge crack in a shape memo
