FIG. 3.19 Simulation of the forming-expanding process of the grooved tube. Expansion until a cylindrical shape with 20mm inner diameter is
obtained.

FIG. 3.20 Simulation of forming sequence of final stent bell-shaping process: (A) the final shape forming tool is modeled by a rigid surface, repre-
sented by a line corresponding to the external profile; (B) finite element model of the expanded stent [54].
