| Research Abstract |
So far, several types of the parameters have been proposed to detect plastic strains by electron backscatter diffraction (EBSD). However, there is little information on the most suitable parameters through the detailed discussion. There is also limited information on the evaluation of fatigue damage by EBSD. In the present study, the procedures which enable to evaluate fatigue damage quantitatively have been suggested by introducing statistical approaches. The applicability of the procedures has also been discussed by comparing the parameters formerly proposed.
