Lacerative properties of the human skin during impact
Published September 07, 1977 by International Research Council on Biokinetics of Impact in Switzerland
372 tests were performed for the investigation of lacerative properties of human skin during impact. The skin specimens were obtained from different body regions of 4 living persons supplied by plastic surgeons after operations, and anther group of specimens were from a fresh unembalmed cadaver.
It was found that the severities of lacerative injury of skin depended on the applied load, the lacerative resistance, and on the geometrical shape of impactor. These experimental results were shown to be in agreement with the theoretical calculations. The results also showed that the lacerative resistance of human skin is dependent upon body region, human subject and age.
All of the experimental results were dependent on the lacerative orientation in relation to Langer's lines. They were in accordance to the statistical results that the lacerative facial injuries along the lines were most frequently found in traffic accident investigations.
The choice of lacerative resistance for simulating facial skin of anthropometric dummy can be determined by both experimental and statistical results
