摘要
A finite element program has been developed and applied for the simulation of two-dimensional and axisymmetric solidification processes to predict temperature history, shrinkage and porosity distributions. A contact thermal resistance was introduced for handling the interface heat transfer between molds and casting with exothermic powders, chills, and pads. The developed program was tested by simulating axisymmetric sand castings of steel and steel piston crown, and an axisymmetric low pressure die casting of an aluminum alloy. The numerical predictions were in good agreement with the experimental results available in the literature. © 1990.
