Objectivies and Approach

Casting is a very complex process of paramount importance for many industrial sectors such as the automotive and the nautical industries. Although a great deal of progress has been made in the computer modelling of casting processes, there is still need to better understand the physical phenomena occurring in casting problems. This requires investigation in different areas including numerical modelling of mould filing, prediction of thermal stresses in a solidifying material, micro and macro modelling in order to predict material microstructures, experimental identification of material properties and defect formation.

The high computing time required for the solution of 3D industrial casting processes using advanced computational methods such as the finite element method involves days of computation on a fast workstation. The use of parallel computing techniques could allow a cost effective solution of the problem by means of clusters or "farms" of workstations using advanced operating systems, such as PVM.

The specific project objectives are the following: In a first phase, advanced constitutive and enhanced finite element computational models will be developed to accurately predict the coupled thermomechanical behaviour of cast specimens during solidification. The second part of the project is devoted to the integration of the coupled thermomechanical and frictional contact models in a parallel computing environment using networks of workstations and advanced operating systems for parallel processing, such as PVM. Finally, the resulting parallel codes will be validated in the analysis of solidification in industrial casting problems for which experimental results will be available from the industrial partners.
