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.
Journal ArticleDOI
On the Effects of Modeling As-Manufactured Geometry: Toward Digital Twin
TL;DR: In this paper, a crack path prediction method based on as-manufactured component geometry is proposed to resolve the crack-path ambiguity in the Digital Twin concept, which is also related to our work.
Journal ArticleDOI

TL;DR: In this article, three-dimensional elasto-viscoplastic finite element analyses are performed to develop a response surface for the tensile stress in the particle as a function of the strain level surrounding the particle, parent grain orientation and particle aspect ratio.
