説明

Such high polymer materials as silicone gel are used for the shock absorber in sport shoes. In the stress analyses of shoe soles, it is difficult to detemine the load conditions by measured pressure. Because the distribution of pressure upon the shoe sole changes according to the stiffness of these materials, which generally show the nonlinear behavior in the stress-strain relations. So a stress analysis method considering the statically indeterminate problems is proposed to identify the pressure distributions on variable shoe sole models. The compression testing of nonlinear materials is carried out and the results of experiments indicate the effectiveness of the proposed method. And the strain energy of a shoe sole model is calculated under the condition of the identified load and compared with the result using the measured pressure directly.
