Effect of mushy zone constant in Voller-Prakash model on keyholing behaviour in laser powder bed fusion simulation

This paper is a study of the model constant of the Voller-Prakash model: the mushy zone constant (C), which determines the flow resistance in the mushy zone during metal solidification. A drag force-liquid fraction relation was derived, assuming that the dynamic and static pressures were equal. The...
