[Preliminary study of biomechanic property on human forethigh skin].
HLC0-I biomechanical living-tissues testing mechanic was adopted for testing the biomechanical property of normal adult forethigh skin. The figures acquired were calculated using one dimension strain energy function and the constitutive equation of mono-way stress and strain was established. The results showed that the relationship between stress and strain could be expressed by the exponential function. The rise of stress was not evident when the strain was lower than 1.2, but the stress rose much sharply when the strain was higher than 1.2. The curves were nonlinear. This suggests that when we sew up a wound or perform skin transplantation, the strain should be lower than 1.2.
