Thermo-fluid modeling of direct chill casting of metal alloys using an inverse finite element method
(Publ by Computational Mechanics Inc, 1992)
Direct chill (DC) casting is used extensively in the production of wrought nonferrous metals and alloys, particularly in the aluminum industry. For alloys, a semi-solid region known as the “mushy zone” and defined by the ...
Two-phase model for processing materials in semisolid state
(Affiliation: Worcester Polytechnic Inst, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.Worcester Polytechnic Inst, Worcester, United States, 1998)
The importance of processing of metal and metal matrix composites in semisolid state is increasing quite rapidly due to the distinct advantages it offers over similar methods of near-net-shape making. In this investigation ...
Differential evolution based identification of automotive hydraulic engine mount model parameters
(2000)
Hydraulic engine mounts are commonly used in an automotive applications, and numerical models exist for performing full-vehicle noise, vibration and harshness (NVH) studies by means of multibody simulation. The parameters ...
An Algorithm for the Selection of Physical System Model Order Based on Desired State Accuracy and Computational Efficiency
(American Society of Mechanical Engineers (ASME), 2003)
In recent years, algorithms have been developed to help automate the production of dynamic system models, The focus of this development has been to create procedures and algorithms that use modeling metrics for generating ...
A modular modeling approach for the design of reconfigurable machine tools
(Affiliation: Department of Mechanical Engineering, University of Michigan, Ann Arbor, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Ersal, T.Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2004)
A new generation of machine tools called Reconfigurable Machine Tools (RMTs) is emerging as a means for industry to be more competitive in a market that experiences frequent changes in demand. New methodologies and tools ...
The Solid Mechanics of Cancer and Strategies for Improved Therapy
(2017)
Tumor progression and response to treatment is determined in large part by the generation of mechanical stresses that stem from both the solid and the fluid phase of the tumor. Furthermore, elevated solid stress levels can ...
Thixotropy of semisolid metals
(Materials Research Society, 2000)
Understanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is ...
Design of ball-milling experiments on Bi2Te3 thermoelectric material
(2013)
In this work, factorial ball-milling experiments have been applied to Bi2Te3 material, for the first time, aiming to investigate the effect of the main process parameters on the structural features and thermoelectric ...
Structure-based turbulence modeling for wall-bounded flows
(2000)
The performance of Reynolds stress transport (RST) models in non-equilibrium flows is limited by the lack of information about two dynamically important effects: The role of energy-containing turbulence structure ...
Ideal physical element representation from reduced bond graphs
(2002)
Previous research has demonstrated that bond graphs are a natural and convenient representation to implement energy-based metrics that evaluate the relative 'value' of energy elements in a dynamic system model. Bond graphs ...
