在体外研究中用作人类皮肤替代品的猪皮肤的机械性能对于许多应用（包括手术和生物力学）都很重要。本研究在猪皮肤上进行了两个方向（平行和垂直于脊柱）取样的单轴拉伸实验，以研究拉伸应力应变响应。实验结果表明，猪的皮肤表现出各向异性和非线性行为。采用奥格登模型来描述猪皮肤的拉伸行为。 Ogden 模型为动物皮肤组织在低变形范围（伸长曲线的第一阶段和第二阶段）提供了良好的拉伸曲线拟合。
The mechanical properties of a pig’s skin which is used as the human skin substitute in the studies carried out in vitro are important for a number of applications, including surgery and biomechanics. In this study, uniaxial tensile experiments were performed on porcine skin for the two directions of the samples taken (parallel and perpendicular to the spine) to investigate the tensile stress-strain response. The experimental results show that pig’s skin exhibits anisotropic and non-linear behavior. The Ogden model was adopted to describe tensile behavior of the pig’s skin. The Ogden model provides a good tensile curve fit for the animal skin tissue in the low range of deformation (first and second stage of elongation curve).
