As-built specimens were then machined and the initial yield surface was determined for three printing orientations based on the yield stress definition for 0.005 % plastic offset strain. The as-received, wrought material was additionally tested using the same tension–compression-torsion conditions to compare the mechanical behaviour of AM and wrought SS316L. The sizes of yield surfaces elaborated for LPBF-M specimens increased along the tensile and compressive directions and shrunk when torsion was applied, as compared to the as-received specimen.

1. | Dubey V.P., Kopeć M., Pawlik M.♦, Wood P.♦, Kowalewski Z.L., Effect of Build Orientation on the Yield Surface of Stainless Steel 316L Fabricated by Laser Powder Bed Fusion Melting (LPBF-M), BSSM, 18th International Conference on Advances in Experimental Mechanics, 2024-09-03/09-05, Liverpool (GB), pp.1-2, 2024 Abstract: The Laser Powder Bed Fusion Melting (LPBF-M) method was used to additively manufacture stainless steel 316L tubes in three different orientations. The yield surface approach was implemented to assess the variation of mechanical properties within the as-built specimens. Yield surfaces were determined for each build orientation based on the definition of yield stress for 0.005% plastic offset strain. The initial yield surfaces obtained for the as-built material exhibit anisotropic behaviour, possibly resulting from the preferred grain orientation developed during LPBF-M processing. Affiliations:
