Authors Abstract
Content
Twelve unembalmed human cadavers were tested for lower abdominal injury tolerance and mechanical response. The impacts were in an anterior-to-posterior direction and the level of impact was primarily in the lower abdomen at the L3 level of the lumbar spine. The impactor mass was either 32 kg or 64 kg. The impactor face was a 25 mm diameter aluminum bar, with the long axis of the bar parallel to the width of the cadaver body.
In this paper, mechanical response is presented in terms of force-time and penetration-time histories, and force vs. abdominal penetration cross-plots. Injury tolerance is described in terms of post-impact necropsy findings and AIS ratings.
Based on our studies, the lower abdomen of the unembalmed human cadaver is much less stiff than is suggested by previous research, and the stiffness is velocity and mass dependent, as is suggested by the correlation coefficients presented in this paper. Force-time history and force-penetration response corridors are presented.
