Abstract
Skin possesses the fibrous tissue composed from the extracellular matrices such as collagen and elastine, and its macroscopic mechanical properties depend on the microstructure in fibrous skin tissue. The configuration and distribution of microscopic mechanical properties in extracellular matrices create the microscopic inhomogeneity inside the skin tissue, hence, it is necessary to analyze this microscopic homogeneity in order to predict the deformation and strength including the micrstructure of skin tissue. Recently, an asymptotic homogenization method is applied for a various materials since the microscopic inhomogeneity can be easily considered. Its reliability of this technique becomes higher and higher. Here, computational simulation is performed by the asymptotic homogenization for incompressible hyper elastic body of skin tissue with fibrous microstructure based on the updated Lagrangian formalizm and rate form of virtual work principle.
