要約(英語): In this research, crack formations and developments in ice on ice breaking by pulsed power were investigated using high-speed camera. The pulsed arc discharge was created in water using Marx generator. Shock wave was produced and propagated in water, and then the ice surface was loaded by pressure of shock wave. Cracks were formed inside ice body, and were developed. A velocity of crack development of 2900 m/s was obtained at a discharge peak power of 160 MW from images of high-speed camera. It was found that the velocity of crack development was increased with increase of discharge peak power.
