Statistical analysis to assess porosity equivalence with uncertainty across additively manufactured parts for fatigue applications
Justin P. Miner, Sneha Prabha Narra
Previous work on fatigue prediction in Powder Bed Fusion - Laser Beam has shown that the estimate of the largest pore size within the stressed volume is correlated with the resulti…
Trajectory Optimization for Spatial Microstructure Control in Electron Beam Metal Additive Manufacturing
Mikhail Khrenov, Moon Tan, Lauren Fitzwater +2
Metal additive manufacturing (AM) opens the possibility for spatial control of as-fabricated microstructure and properties. However, since the solid state diffusional transformatio…
Enforcing the Principle of Locality for Physical Simulations with Neural Operators
Jiangce Chen, Wenzhuo Xu, Zeda Xu +3
Time-dependent partial differential equations (PDEs) for classic physical systems are established based on the conservation of mass, momentum, and energy, which are ubiquitous in s…
Capturing Local Temperature Evolution during Additive Manufacturing through Fourier Neural Operators
Jiangce Chen, Wenzhuo Xu, Martha Baldwin +5
High-fidelity, data-driven models that can quickly simulate thermal behavior during additive manufacturing (AM) are crucial for improving the performance of AM technologies in mult…
