Computational analysis of the effects of geometric irregularities and post-processing steps on the mechanical behavior of additively manufactured 316L stainless steel stents
Fig 14
Contour plots of the von Mises stress σvM on the outer surface of the laser powder bed fused (L-PBF) stents under compression of 0.8 mm.
A: Stents in the as-built and B: in the heat treated material condition illustrated in the front (top row) and the side view (bottom row). StentAB, stentHT and stentEP-HT correspond to the reconstructed L-PBF stents in the as-built (AB), heat treated (HT), and electropolished and HT (EP-HT) conditions, respectively. StentCAD,AB and stentCAD,HT correspond to the as-designed stent CAD models with the as-built and heat treated material properties, respectively.
