Cold drawing of 316L stainless steel thin-walled tubes: Experiments and finite element analysis

Abstract: Drawing process of thin walled tubes used to fabricate catheters and stents for medical applications was studied. Medical use needs accurate dimensions and a smooth finish of the inner and outer surfaces. This paper deals with 316L stainless steel tubes which are manufactured by means of cold drawing with or without inner plug (mandrel drawing and hollow sinking, respectively). To improve the quality of the finish of the tubes, numerical modelling can be used. In this way, a thermomechanical study of the drawi… Show more

“…The experimental results only permit to determine macroscopic data, but failure criteria calculation needs the local strain and stress fields to be evaluated. These fields can be evaluated by means of FEM (Palengat et al, 2013;Beland et al, 2011).…”

“…Table 6 collects the values of σ zf /2 k found in the literature. Concretely, in the column 1, the literature FEM simulations values (LFEM); in column 2, the literature experimental ones (LE); and, in the column 3, the obtained results by the UBM model proposed in this work (UBM) using the same parameters values that in the above mentioned work [48]. The parameters values are, concretely, α = 13 • , β = 11 • , µ 1 = 0.10; µ 2 = 0.05, and the cross-sectional area reductions r = 0.10, 0.16, and 0.20.…”

“…Considering that the initial wall thickness of the tube is 2.34 mm, that eight mesh elements have been included along the wall thickness of the tube according to our experience and to previous works found in the literature [48], and that the mesh elements are quadrilateral, then the starting mesh size is around 0.3 mm. The tube material considered in the FE model is the alloy UNS C11000 (CDA-110 in DEFORM F2™), and it has been imported from its library.…”

“…In recent years, the expansion of circular tubes has drawn more and more attention in much more critical applications where accurate dimensions, smooth surface finishes, and long-term safe and trouble-free operations are of great importance such as catheters for medical application, passive energy absorbers in automotive industry, etc. [3][4][5].…”
