      Mathematical and computational modeling of die filling in semisolid metal processing 

      Alexandrou, Andreas N.; Bardinet, F.; Loué, W. (1999)
      A 'Bingham type', or Herschel-Bulkley constitutive relation capable of describing correctly the bulk behavior of the semisolid slurry is introduced. This relation is implemented in a modified version of the casting simulation ...

      Numerical simulation of die filling in semisolid metal processing 

      Bardinet, F.; Alexandrou, Andreas N.; Loue, Willem (Affiliation: WPI, Worcester, United StatesCorrespondence Address: Bardinet, FrancoisWPI, Worcester, United States, 1997)
      Semisolid Metal Processing offers distinct advantages over other near-net-shape technologies, such as a more homogeneous microstructure, less porosity and thus excellent mechanical properties. A perfect control of die ...

      Sharkskin and oscillating melt fracture: Why in slit and capillary dies and not in annular dies? 

      Delgadillo-Velázquez, O.; Georgiou, Georgios C.; Sentmanat, M.; Hatzikiriakos, Savvas George (2008)
      The sharkskin and stick-slip polymer extrusion instabilities are studied primarily as functions of the type of die geometry. Experimental observations concerning the flow curves, the critical wall shear stress for the onset ...
