Mathematical and computational modeling of die filling in semisolid metal processing
(1999)A 'Bingham type', or HerschelBulkley 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
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Bardinet, FrancoisWPI, Worcester, United States, 1997)Semisolid Metal Processing offers distinct advantages over other nearnetshape technologies, such as a more homogeneous microstructure, less porosity and thus excellent mechanical properties. A perfect control of die ...

Article
On the early breakdown of semisolid suspensions
(2007)Semisolid materials are suspensions of metal alloys which are processed while in a mushy state. In this state, the suspensions behave as viscoplastic materials with timedependent material properties. During processing, ...

Three dimensional flow of thixotropic materials in a channel with a sudden expansion using a phenomenological constitutive relation
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.WPI, Worcester, United States, 1996)A constitutive relation is proposed that is capable of predicting a wide range of experimental rheological behavior depending on the proper choice of the parameters. The model represents the otherwise discontinuous Bingham ...
