J-integral analysis: An EDXD and DIC comparative study for a fatigue crack
International Journal of Fatigue, 2020 Synchrotron Energy Dispersive X-ray Diffraction (EDXD) and Digital Image Correlation (DIC) have been applied to map simultaneously the 2D elastic strain and displacement fields of a propagating fatigue crack in the HAZ of a welded Cr2Ni4MoV bainitic ...
