Abstract—Shrinkage characteristic of US 413 cast aluminium alloy has been discussed in the current study. The decrease in specific volume leads to shrinkage in castings and it can be envisaged as a defect. The shrinkage porosity has been studied using finite difference based casting process simulation software. The shrinkage characteristic has been quantified using arithmetical formula. A three dimensional solid model of the shrinkage defect has been constructed using CAD. Shrinkage characteristic has also been quantified through experimental validation studies and compared well with casting process simulation. Influence of casting shape on the shrinkage characteristic has been studied in this paper
