Thermophysical Properties Necessary for Advanced Casting Simulations

Numerical modelling of casting processes has become an up-to-date standard in industry, aiming at a short term design of modern casting with optimized properties. This paper outlines the present modelling approaches and gives an overview on thermophysical properties (parameters) necessary for such simulations. Mould filling and heat transport simulations, stress and strain predictions, Cellular Automaton and phase-field techniques, and recent multiphase volume average approaches are discussed. The number of necessary material properties is shown to be directly correlated to the amount of complexity considered in the corresponding modelling approach.
