摘要

In clinical practice, fast assessment of contact pressure is usually calculated by Laplace’s Law, which neither providesndetailed surface geometry for soft materials of the leg, nor offers sufficient predictive power for designing highperformancensportswear. To bridge this gap, this paper describes a finite element (FE) model of sports tights that wasndeveloped with a detailed anatomic male leg model to predict the compression effects of high-performance sportswear.nNon-linear elastic material was applied on the sportswear material to model the large deformation behavior.nExperimental validation on athletes was performed. A reasonable agreement was found in the experimental validation.nSuitable profiles were achieved along the height of the leg, in terms of both contact pressure and clothing deformationn(true strain or logarithmic strain). The maximum contact pressure (2222 Pa) occurred on the posterior of the ankle,nwhile the maximum principal true strain of the sports tights occurred on the edge of the upper thigh. This study indicatesnthat the proposed FE model is useful for the assessment of contact pressure distribution in sportswear.
