For simulating the dynamic fracture behavior of cast aluminum components, the effects of the stress triaxiality and strain rate on the ductile fracture properties of cast aluminum alloy were characterized. It is investigated that the fracture strain has the strong dependencies of average stress triaxiality and strain rate. Then, the fracture model consisting of average stress triaxiality, strain rate and fracture strain was applied to the dynamic failure simulation of the cast aluminum component. As a result, the usefulness of the fracture model was validated.
