文摘

Human foot supports the body weight and absorbs the dynamic impact force from the ground by the upward and tension forces developed in bones, joints, plantar fascia and ligaments. Both the arch deformation and the load-bearing characteristics of the foot during standing are significantly influenced by abnormal conditions such as the standing on high-heel shoes or obstacle cleats. The purpose of this paper is to numerically investigate the biomechanical responses of human foot to the height of high-heel shoes and a rigid hemisphere cleat by the nonlinear finite element analysis. An anatomically detailed 3-D finite element bone model was generated from the real MRI data of human foot. The nonlinear behavior of plantar fascia was implemented by Mooney-Rivlin material model, and the finite element model was validated through the comparison with the existing numerical data. And the biomechanical characteristics such as the peak deformation and the peak effective stress were investigated to the heel height and the location of a rigid hemisphere cleat.
