Abstract
Impact biomechanics of the pig liver and the spleen were measured in "free-fall" direct impact test. Test pieces of the liver and the spleen were obtained from edible pigs in order to examine the injury criteria and tolerances. Impact speed, relative compression and maximum impact force are reviewed as explanatory variables for injury severity. Relative compression of organ shows high correlation coefficient in all cases of the liver and the spleen test. The tolerances of the organ with artificial blood perfusion in the physiological blood pressure are little smaller than that of without perfusion.
