Abstract
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
