Integration and use of diesel engine, driveline and vehicle dynamics models for heavy duty truck simulation
(1999)
An integrated vehicle system simulation has been developed to take advantage of advances in physical process and component models, flexibility of graphical programming environments (such as MATLAB-SIMULINK), and ever ...
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 ...
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 ...
Optical and electrical properties of selectively delta-doped strained InxGa1-xAs/GaAs quantum wells
(1996)
We report here an investigation of selectively delta-doped strained InGaAs/GaAs quantum wells. Electronic structures of the systems were calculated by self-consistently solving the Schrödinger and Poisson equations and the ...
Identification of hysteretic systems using the differential evolution algorithm
(Affiliation: Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United KingdomCorrespondence Address: Kyprianou, A.Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United Kingdomemail: Mep96Gak@sheffield.ac.uk, 1998)
In system identification, it is well-known that any non-linear in the parameters system, possesses a complicated error surface with many local minima. In this case the conventional algorithms, such as those based on least ...
Atemplate-based modeling approach for system design: Theory and implementation
(1996)
Previous research has developed search algorithms for deducing Proper Models (minimum complexity models with physically meaningful parameters) of dynamic systems. It has also been proposed that these Proper Models can be ...
Numerical simulation of injection mold filling for semi-solid materials
(ASME, 1995)
Processing of metals and metal matrix composites in the semi-solid state is an emerging new technology and is becoming increasingly popular. This method provides several advantages over the traditional liquid state processing ...
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 ...
