Résumé
Metal Additive Manufacturing (AM) technologies, particularly Wire Arc Additive Manufacturing (WAAM), have revolutionized the production of large-scale metallic components with complex geometries and tailored material properties. To adopt WAAM to the industrial application, it requires a high structural integrity, especially in aerospace, automotive, and shipbuilding industries. A thin wall ER70S-6 plate built using WAAM was evaluated through uniaxial tension tests, following ASTM E370-20 protocol, at strain rates ranging from 0.01 s?¹ to 0.5 s?¹. The additive manufactured plate size was 250 mm x 140 mm x 3 mm. Specimens were extracted using a wire electrical discharge machine to cut to 20 specimens per plate. Tests were conducted with two surface conditions: raw and ground. Observations from this study noted that the error range of the test results was reduced when the specimens were ground. Importantly, it was observed that the material stiffness is significantly influenced by the surface conditions, a key finding of the research. A positive strain rate sensitivity was observed where the strength behaviour at 0.1 s?¹ and 0.5 s?¹ strain rates was found to be higher than findings from specimens tested at 0.01 s?¹ strain rate. Findings from this research can be expanded to develop material models for the simulation of materials/structures developed using WAAM.
