Abstract The mixed-mode, elastodynamic state of stress in the neighborhood of a constant-velocity crack tip is used to generate numerically unsymmetric isochromatics. Unsymmetry associated with the third-order terms of a mixed-mode stress field, with and without the Mode II singular stress term, is also investigated. In extractingK I from an unsymmetric isochromatic pattern, errors in the Mode I fracture parameters due to the assumed presence ofK II in aK I stress field were found to be significant when data are taken more than 4 mm from the crack tip.
