Description

The impact strengths of strengthened porcelain bowls were evaluated using an impact examination machine based on JIS S 2402. A strain waveform developed upon impact was measured by a strain gauge adhered to the inside surface on the porcelain bowl. The deformation of the porcelain bowls was observed by high-speed camera. The strain waveforms showed two noteworthy peaks. The first peak was found to be caused by the initial impact, and the second peak was found to be caused by the restorative force generated by the deformation of bowl, which acted as a backstop. The high-speed camera also revealed that the bowl re-collided with the hammer or pushed the hammer again as the bowl returned to its original shape and position, resulting in the second peak. The variation of the strain waveform was found to be related to the size of bowl and the open angle of the backstop.
