    Abstract

    Two established optical methods are described briefly with refinements to allow accurate near-tip measurements for three-dimensional cracked body problems. Several illustrations of their use are presented and compared with numerical results.

    Keywords:

    stress-intensity factors, three-dimensional photoelasticity, moiré interferometry, dominant eigenvalues, fracture mechanics, fatigue (materials)
