"Easy to move" is one of the most important functions for apparels, especially for the sportswear. Skin strain is one of the factors to provide for this "Easy to move". The purpose of this study is establishment of the polygon strain analysis technique on 3D-CG and application to the skin strain simulation. We derived an analytical technique of the polygon strain using the idea of the minute strain of elastic material. We constructed 3D-CG model that imitate the human body, and made posture that knee was flexed, hip was flexed or hip was extended. We calculated the polygon strain using this model and compared with the skin strain measured on the human body. There is a significant correlation between the polygon and the skin strain (r=0.972, p<0.01). This result suggests that skin strain simulation is effective to the quantification of the skin strain that is important to design the sportswear.
