The mechanical properties of the clustered shrinkage pores in high-pressure die cast aluminum alloy ADC12 were evaluated through the serial sectioning experiment and the image-based finite element analyses. We have investigated the effect of pores on the fatigue strength, and found a mechanical significance of the clustered shrinkage pores, which considerably undermines the fatigue strength of die cast aluminum alloys. In this study, we constructed twenty three unit cell models for the homogenization analysis based on the three-dimensional image of a clustered shrinkage pore. From the homogenization analysis and uniaxial extension analysis, we obtained the equivalent elastic constants and the micro stress concentration factor as a function with respect to the porosity volume fraction.
