چکیده
In this study we have investigated in 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 on excised human skin from the back. 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). Keywords— Skin, Langer’s Lines, Histology

Strain rate effects on the failure characteristics of excised human skin
Introduction Skin is a complex, multi-layered material which exhibits non-linear, anisotropic and viscoelastic behaviour. Its structure is complex and can be broadly divided into three main layers: the epidermis, the dermis and hypodermis. The thickest of these layers, the dermis, consists of strong stiff collagen fibres which govern many of the mechanical properties of human skin [1]. The mech...
متن کاملPartial purification of tomato fruit peroxidase and its effect on the mechanical properties of tomato fruit skin.
Peroxidase (EC 1.11.1.7)-mediated stiffening of cell walls within the fruit skin of tomato is hypothesized to regulate fruit growth. However, to date, there is no experimental evidence demonstrating that peroxidase affects the mechanical properties of skin tissue. Here, the mechanical properties of skin strips excised from a range of fruits at different ages were determined using an 'Instron' u...
متن کاملCharacterization of the anisotropic mechanical properties of excised human skin.
The mechanical properties of skin are important for a number of applications including surgery, dermatology, impact biomechanics and forensic science. In this study, we have investigated the influence of location and orientation on the deformation characteristics of 56 samples of excised human skin. Uniaxial tensile tests were carried out at a strain rate of 0.012 s(-1) on skin from the back. D...
متن کاملDetermination of the mechanical properties of the skin of pig foetuses with respect to its structure.
Skin is an important barrier protecting the organism against external environmental factors. Determination of its mechanical characteristics as regards its structure has significant scientific and application value. In this work, uniaxial tensile tests were conducted to determine the basic mechanical parameters of skin with respect to its structure. The subject of the study were skin samples ta...
متن کاملDevelopment of the mechanical properties of engineered skin substitutes after grafting to full-thickness wounds.
Engineered skin substitutes (ESSs) have been reported to close full-thickness burn wounds but are subject to loss from mechanical shear due to their deficiencies in tensile strength and elasticity. Hypothetically, if the mechanical properties of ESS matched those of native skin, losses due to shear or fracture could be reduced. To consider modifications of the composition of ESS to improve homo...
