| Abstract Scope |
Hot tear in steel casting is an unacceptable defect found in final cast product. A hot tear is a fracture formed in the mushy zone during solidification that is not completely solidified with a high fraction of solid due to applied tensile strain. In this work the calculation of solidification and deformation was done using a commercial software with a user-defined constitutive model. The shrinkage porosity information is coupled to the solid deformation constitutive model to calculate the material damage. A viscoplastic model including damage was applied to predict the hot tear formation in mold steel alloy casting. Hot tears are to be expected in region of extensive damage. A good correlation between experimental findings and predicted damage is observed. |
