TL;DR: In this article, the authors discuss primary detrimental hurdles that have plagued effective modeling of additive manufacturing methods for metallic materials while also providing logical speculation into preferable research directions for overcoming these hurdles, including high performance computing, multiscale modeling, materials characterization, process modeling, experimentation, and validation for final product performance of additively manufactured metallic components.

TL;DR: In this article, a multi-scale heat transfer modeling framework was developed to investigate the EBM process of fabricating FGMs, which is capable of accounting for the material properties and electron beam properties that depend on experimental setup.

TL;DR: In this article, a new heat source model was developed based on Monte Carlo simulations performed to obtain the distribution of absorbed energy through electron-atom collisions for an electron beam with a kinetic energy of 60 keV hitting a Ti---6Al---4V substrate.

TL;DR: In this paper, the authors investigated the differences in deformation mechanisms between single-point incremental forming and cumulative double-sided incremental forming (ADSIF) and showed that the presence of the supporting tool in ADSIF elicits substantial differences in the plastic strain, hydrostatic pressure, and shear strains as compared to SPIF.

TL;DR: In this article, an approach for incorporating thermodynamically consistent properties and microstructure evolution for non-equilibrium supercooling, as observed in additive manufacturing processes, into finite element analysis is presented.
