For X-ray CT images of cast aluminum alloy under fatigue test, we have tried to identify displacement field and its corresponding strain field. Two techniques are employed: (i) digital template matching in sub-pixel precision to maximize image correlations for the regions where textures are well captured and (ii) PDE for linear elastic problem, i.e., FEM to globally interpolate the field for the regions where there are no textures. Two-dimensional identifications are presented to confirm the usefulness of the two techniques.
