Anisotropic yield surfaces of additively manufactured metals simulated with crystal plasticity
Abstract
The mechanical anisotropy created by additive manufacturing (AM) is notyet fully understood and can depend on many factors, such as powdermaterial, manufacturing technology and printing parameters. In thiswork, the anisotropic mechanical properties of as-built, laser powderbed fusion (LPBF) austenitic stainless steel 316L and titanium alloyTi-6Al-4V are investigated through crystal plasticity simulations.Periodic representative volume elements (RVEs) are used that arespecific to each material. The RVE for austenitic stainless steelconsists of FCC crystals with a crystallographic texture measured byX-ray diffraction. The martensite microstructure of Ti-6Al-4V is captured with a multi-scaleRVE, including internal lamellar structures, using HCP crystals and asynthetically generated texture. For both materials, the crystalplasticity parameters are calibrated against tensile tests carried outon dog-bone specimens printed in different orientations. The RVEs,calibrated to experiments, are applied in virtual material testing andsubjected to multiple load cases to generate the Hill-48 and Yld2004-18pyield surfaces of the materials.
