[0002] At present, the research on bubble icebreaking in China is developing rapidly. In the field of single bubble icebreaking, the dynamic behavior of single bubble under complex boundaries, the mechanism and ability of single bubble icebreaking, the impact response of single bubble icebreaking on aluminum plates, and the coupling response of single bubble icebreaking and structure at multi-angle boundaries have been studied.
