چکیده انگلیسی
This is the second of two papers that analyze the effects of porosity upon the fracture properties of the die-cast AM60B magnesium alloy. This paper investigates the effects of the size and location of porosity using finite element simulations. Failure models were developed for the cases of a pore centered in the cross-section, a volume of material intact in the casting, and samples removed from the casting for die-cast materials. The predicted fracture strains for a centered pore compared favourably with a previously developed analytical model. The fracture strains of samples removed from an AM60B casting and characterized using X-ray tomography were predicted with an average error percentage of 6.7%.
