Effect of mushy zone constant in Voller-Prakash model on keyholing behaviour in laser powder bed fusion simulation
Description/Abstract:
This paper is a study of the model constant of the Voller-Prakash model: the mushy zone constant (C), which determines the flow resistanc...

Influence of recoil pressure, mushy zone flow resistance and reflectivity on melt pool shape in laser powder bed fusion simulation
Description/Abstract:
Melt pool dimensions (depth: <i>D</i> and width: <i>W</i>) are strongly correlated with defects generated in laser powder bed fusion. The...
