The authors have shown that the stress intensity factor, K, can be analyzed by measuring the distribution of the sum of the principal stresses around the crack tip by an infrared stress measuring device, SPATE-8000. The errors of the measured K-values for CT-specimens are at most 10∼20%, and they decrease with the decreasing amplitude of the applied cyclic stresses. The method has been applied to the measurement of K for a surface crak. Finally, the method for analyzing K1 and K11 for mixed mode cracks has been proposed.
