Abstract Scope |
This additive manufacturing benchmarking challenge (CHAL-AMB2022-04-MaTTO) asks the modelling community to predict the average stress-strain response of tension specimens that were excised from pieces of IN625 manufactured by laser powder bed fusion (L-PBF). The uniaxial tension tests are gripped in clevises, conducted at quasi-static strain rates under displacement control, and strain is measured with an extensometer. With respect to the build direction, multiple tensile orientations (parallel, perpendicular, and intervals between the extremes) were selected to measure the anisotropy and compare between L-PBF scan strategies, which are an X-only raster and an X-Y raster (90-degree scan rotation between X and Y scan paths). The challenge provides information on chemical composition, grain structure (electron backscatter diffraction measured on three orthogonal directions) and pore structure (volume-based measurements via X-Ray computed tomography) from unused blocks of material manufactured on the same build plate. |
