Properties of the Temporary Cavities in Water Produced with Different Projectiles / 第三军医大学学报

ABSTRACT

The processes of temporary cavitations produced with 7.62mm bullet, 5.56 mm bullet and 6.35mm spherical steel-pellet in water were recorded with a high speed (8,000 frames per second) camera to investigate the traumatic mechanism of fragments with high velocity and small mass. The temporary cavities produced with above mentioned projectiles were different because of their different ballistic behaviors. The shape and size of the temporary cavitv and the time of its formation were closely related to the density of the adjacent tissues and also to the extent of the tissue damage. Thus the study on the temporary cavitations after projectiles of high velocity but small mass is of clinical significance.
