Outline of Final Research Achievements

We investigated the relationship between internal stress fields, crack propagation behaviors and fracture surface qualities during wheel scribing of glass sheets. For this purpose, a wheel scriber that can operate in scanning electron microscope was developed. In addition, we tried to visualize the crack propagation behavior using a high-speed camera. These observation results showed that the fracture surface morphology depended on whether the penny cracks which appeared under the wheel were connected with each other. We also measured the phase difference distributions in glass sheets just after scribing using a high-speed polarization camera. As a result, it was found that the measured phase difference distribution included information about the crack propagation behavior, and this information could be used for the estimation of the fracture surface morphology. An in-process estimation method for the fracture surface morphology was therefore developed.
