Abstract

This study investigates the influence of location, gender and orientation on the deformation characteristics of 55 samples of human excised skin. Uniaxial tensile tests were carried out at a strain rate of 0.012s− 1 on excised human skin taken from the back of deceased subjects. The deformation characteristics of skin (Ultimate Tensile Strength (P<0.0001), Failure Strain (P=0.0177), Young’s Modulus (P<0.0076), Initial Slope (P=0.0375) and Strain Energy (P=0.0101)) were found to be dependent upon the orientation of specimens with respect to the Langer’s Lines. The location of specimens on the back was also found to have a significant effect on the Ultimate Tensile Strength (P =0.0002), the Young’s Modulus (P=0.0017) and the Strain Energy (P=0.005).
