| Abstract Scope |
The complexity of the laser powder bed fusion process makes it challenging to accurately predict the build success, part distortion, surface roughness, local microstructures, etc. Additionally, the high cost of materials and time further highlight the importance of accurate simulations. These AM simulations often rely on numerous assumptions and “tuning” of variables, and therefore, rigorous benchmark measurements are needed to validate such predictions. Here an overview of the residual strains and stresses of the 3D IN718 AM benchmark artifact measured using energy dispersive X-ray diffraction, neutron diffraction, and contour method will be presented. Submitted elastic strain simulation results will also be compared to energy dispersive X-ray diffraction measurements. |
