The study of high-speed fracture behavior of glass bottles using explosive shock waves

摘要

The fracture mechanics of glass bottles using the underwater Shockwave technique and the recycling process by smashing the glass bottles are discussed. The proposed smashing process can decrease the recycle cost by small grain sizing of the "cullet", which is the crashed glass fragments, and by overlapping the washing process with the recycle pre-processing. In this study, using the commercial beer bottle, the relationship between the "cullet" size and various explosive conditions, i.e. distance, amount, speed and configuration, was clarified.
