The intelligent hybrid technique proposed by Nishioka et al. enables to analyze stress intensity factor in high accuracy and reliability from displacement data obtained by experiments. However, the hybrid technique surfers from inevitable error and noise involved in displacement fields on boundary obtained experimentally. In this paper, a modified intelligent hybrid technique is developed to improve the current technique succeeding its characteristic features. With the hybrid technique proposed, it is possible to reduce the influence of experimental errors on the boundary of the concerned area. Therefore this technique demonstrates to set up the actual boundary condition from experimental data and to analyze stress and strain in the full field on the concerned area in high-reliability and accuracy.
