Modeling fracture properties in a die-cast AM60B magnesium alloy II—The effects of the size and location of porosity determined using finite element simulations

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...
