3-dimensional strain evaluation of compression tights using digital image correlation method

Abstract

In this study, strain distributions of sports compression tights were observed based on image correlation method. An artificial leg jig made of polymer foam was prepared. The artificial leg jig reproduced the shape of the leg of the 3-dimensional computer graphic model of the human body. The strain distributions of the sports compression tights worn by the leg jig were measured by the image correlation method. From the experimental results, strain was measured on the front surface of knee joint. The experimental results were compared with strain calculated by 3-dimensional computer graphic model of human body.
