In general, some defects may generate in manufacture process of an aluminum casting alloy. Therefore it is necessary to measure the overall and local strain with considering the effect of the defects in order to make reliable verification of the material property of the aluminum casting alloy. In this study, first of all, we verified accuracy of Strain Distribution Measuring System using a digital image correlation method by comparison with a strain gauge. Also, we measured the strain distribution of the aluminum casting alloy and compared it with the distribution of the defects inside the specimen which was examined with the X-ray CT system. As the result, we succeeded in measuring the local strain which seemed to be effected by the internal defects, by the present system.
