The temperature image measured in the infrared thermography has a temperature change by the inflow appearance of heat near the free surfaces, and the obtained sum of the principal stresses is not a true value. The data of the sum of the principal stresses were measured on the CNS specimens subjected to seven kinds of mixed-mode loading by the infrared thermography. After estimating the nodal forces from the sum of the principal stresses by an inverse analysis, the error included in the experiment field was modified by the intelligent hybrid method. However, it has the influence by heat conduction on an infrared stress measuring method. Then, the temperature field was corrected in nonsteady-heat-conduction inverse analyses. Thereby, the stress intensity factors of mixed mode were able to be evaluated with less than 6% of error by the infrared hybrid method in consideration of the influence of heat conduction.
