Notes:
The thickness dependency of the temperature image obtained by an infraredthermography was investigated using specimens with three kinds of metal materials of differentheat conduction and four kinds of thickness of the specimens. Then, the infrared hybrid method wasdeveloped to separate each stress components. However, it contains the influence of heatconduction in the infrared stress measurement method. Therefore, heat conduction error will arise inthe infrared hybrid analysis. Then, the new system which corrects the error by an heat conductioninverse analysis was developed. Thereby, the accuracy of the stress intensity factor was able to beraised using heat conduction inverse analysis. Furthermore, the accuracy of hybrid method takingheat conduction into consideration was discussed in comparison with 3-D finite-element analysisand the 2-D infrared hybrid method
