Experimental Investigation of Underwater Blast Injuries to Beagles

doi:10.12382/bgxb.2022.0461

Abstract

Abstract: To study the underwater blast injury modes and thresholds for human, beagle dogs are adopted for gram-and kilogram-level underwater blast tests. The response of beagles to shock wave and bubble pulsation loadings is observed. Air containing organs such as lung and auditory apparatus suffer the most from the shock wave, bubble pulsation, negative pressure and other loads. Whether the head is above the water or not, the brain will be injured to some extent. Under the same underwater blast loading, the damage radius for a beagle in diving position is approximately 2.5 times that of one in swimming position. From experiments, the injury modes and thresholds for beagles under underwater blast are concluded, which can be used to predict and treat underwater shock injuries.

Key words: underwaterblast, underwatershockinjury, shockwave, bubblepulsation
