Paper Abstract

Digital image correlation methodology has been extensively used to estimate full-field displacements according to the gray value of pairs of images, and the extended finite element method is proposed to deal with the discontinuous problem. Inspired by these recent advances, the extended finite element methodology is applied in the expression of the correlation coefficient in this paper. Two-step extended digital image correlation, which has the advantage of self-immunity in the irregular boundary such as crack, hole and so on, is developed to measure the full-field displacements using the partition of unity method as in the extended finite element method
