Recent MMM Lab graduate, Dillon Watring, and collaborators from the National Institute of Standards and Technology (NIST) published work on the extension and experimental evaluation of a void descriptor function, or VDF. The VDF is intended to provide a unique parameter to characterize complex void networks in structural metals, including additively manufactured metals. Compared to other pore-related metrics reported in the literature, the VDF parameter has been shown to be more strongly correlated with ductile-metal failure properties, including fracture location.
