Modeling the evolution of representative dislocation structures under high thermo-mechanical conditions during Additive Manufacturing of Alloys
Markus Sudmanns, Athanasios P. Iliopoulos, Andrew J. Birnbaum +2
Mesoscale simulations of discrete defects in metals provide an ideal framework to investigate the micro-scale mechanisms governing the plastic deformation under high thermal and me…
The interplay of local chemistry and plasticity in controlling microstructure formation during laser powder bed fusion of metals
Markus Sudmanns, Andrew J. Birnbaum, Yejun Gu +4
Additive manufacturing (AM) of metallic components promises many advantages over conventional manufacturing processes through high design flexibility across multiple length scales…
Inference and Prediction of Nanoindentation Response in FCC Crystals: Methods and Discrete Dislocation Simulation Examples
Michail Tzimas, John Michopoulos, Giacomo Po +2
Nanoindentation, a common technique for probing the mechanical properties of crystalline materials, exhibits both surface and bulk-dominated responses that are linked to the parent…
Intrinsic Strain Aging, Boundaries, and Origins of Cellular Substructure in Additively Manufactured 316L
Andrew J. Birnbaum, John C. Steuben, Erin J. Barrick +2
The observation of sub-grained cellular features in additively manufactured (AM)/selectively laser melted (SLM) 316L stainless steel components has remained an interesting, though…
