TL;DR: Sandia National Laboratories, in partnership with US National Science Foundation and Naval Surface Warfare Center Carderock Division, launched a computational challenge in mid-summer, 2012 to predict crack initiation and propagation in a simple but novel geometry fabricated from a common off-the-shelf commercial engineering alloy as mentioned in this paper.

TL;DR: The Sandia Fracture Challenge 3 (SFC3) as mentioned in this paper required participants to predict fracture in an additively manufactured (AM) 316L stainless steel bar containing through holes and internal cavities that could not have been conventionally machined.
Journal ArticleDOI
Direct numerical simulations in solid mechanics for understanding the macroscale effects of microscale material variability
Joseph E. Bishop,John M Emery,Richard V. Field,Christopher R. Weinberger,David John Littlewood +4 more
TL;DR: In this article, the macroscale response of polycrystalline microstructures and the accuracy of homogenization theory for upscaling the microscale response are investigated using a massively parallel finite-element code.
Journal ArticleDOI
The effect of grain size on local deformation near a void-like stress concentration
TL;DR: In this paper, the role of local microstructure on ductile deformation was investigated in brass tensile bars with micro-scale cylindrical holes in situ in a Scanning Electron Microscope (SEM).
