Abstract: Abstract Polycrystals heterogeneities generate stress concentration which can be responsible for premature failure of mechanical parts and thereby need to be considered in mechanical models. A grain’s close neighborhood has shown to significantly impact its… read more here.

Abstract: Abstract A cellular automaton-finite element (CA-FE) model was used to predict the solidification grain structure of permanent mold cast A7086 alloy. In this model, a Gaussian distribution of nucleation sites was adopted, and the Kurz-Giovanola-Trivedi… read more here.
