In this study X-ray CT image is used for meso-scale surface modeling of irregular shaped gas pores in aluminum die cast alloy, followed by image based finite element analysis to evaluate crack initiation point. There is a good agreement between the location of maximum principal stress found by the analysis and location of crack initiation on actual fractured surface. We conclude that mesa-scale image based finite element method is promising for fatigue life prediction of aluminum die cast alloy.
