Material characterization by digital image correlation

Nozawa, Takashi

Digital image correlation technique can monitor local strain deformation on the material surface during mechanical testing and has been developed with conjunction of recent innovation of computer technology. This lecture provides fundamental principle of this technique and brief introduction of recent studies such as characterization of local deformation of weld joint specimen for low-activation ferritic steel by fatigue and evaluation of strength anisotropy of SiC/SiC composites.
