Shrinkage defects occur during solidification and usually occur in the final solidification area. In other words, in order to accurately predict shrinkage defects, flow/solidification analysis by accurate temperature calculation is required. The solidification calculation considers the Fs-T Curve as well. When predicting shrinkage defects, a method that tracks volume, surface area, and modulus of retained melt is used and to predict micro shrinkage, the typical Niyama Criterion is used. AnyCasting also has a feature called Shrinkage Volume which takes into consideration the type of alloy and its shrinkage rate in the final solidification area.
