Mathematical and computational modeling of die filling in semisolid metal processing
(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 ...

Microphase separation in the bulk in ABA triblock copolymer-based model conetworks: Effects of core crowding and loop formation
(2013)The microphase separation in the bulk, in the strong segregation limit, of model conetworks based on end-linked ABA triblock copolymers was investigated by calculating and minimizing the total Gibbs free energy for the ...

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 near-net-shape technologies, such as a more homogeneous microstructure, less porosity and thus excellent mechanical properties. A perfect control of die ...

Permeability calculations in three-dimensional isotropic and oriented fiber networks
(2008)Hydraulic permeabilities of fiber networks are of interest for many applications and have been studied extensively. There is little work, however, on permeability calculations in three-dimensional random networks. Computational ...

University of Puerto Rico, Mechanical Engineering Department, San Juan 00918, Puerto RicoAffiliation: Institute for Problems in Mechanics, Russian Academy of Science, pr. Vemadskogo, 101, 117526 Moscow, Russian FederationCorrespondence Address: Alexandrou, A.N.Semisolid Processing Laboratory, Metal Processing Institute, WPI, Worcester, MA 01609, United States, 2000)The effective use of the semisolid process presumes a good theoretical framework to describe it. The understanding of semisolid behavior should be based upon a combination of basic and empirical knowledge in versatile ...

Time-dependent rheology of semisolid metal suspensions
(Affiliation: Metals Processing Inst, Worcester, United StatesCorrespondence Address: Burgos, Gilmer R.Metals Processing Inst, Worcester, United States, 1999)Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changes with the processing history due ...
