In previous studies, the authors have developed an intelligent hybrid experimental-numerical method based on a variational principle minimizing experimental measurement errors. In this study, the phase shifting method of moire-interferometry is used to clarify deformation behavior near an interfacial crack tip. In this experiment, the bimaterial specimen consists of epoxy and aluminum. Displacement distribution data for the intelligent hybrid method are obtained by the operation of image processing. The stress and strain distributions near the crack tip are visualized from the results of the intelligent hybrid method. Moreover, the higher-order information such as the separate J integral and the stress intensity factors are extracted.
