A flexible string is used at various situations. Especially, there are some products which serves as a purpose by letting them work. Thus, it is necessary to analyze their behavior. In the past studies, dynamic behavior was analyzed when playing fly-fishing. However, the axial elongation is not considered. In fact, the axial elongation affects their behavior such as axial micro vibration or restoring force of the elongation. Therefore, it is necessary to consider the axial elongation to grasp the behavior of the string more exactly. In this study, an accelerated motion of the string such as the casting motion is focused on and analyzed in consideration the axial elongation then appropriateness of the modeling is verified by comparing experimental results and analysis results. Furthermore, relations of the axial elongation and an accelerated motion are investigated. In this report, the behavior is investigated focusing on the speed of the tip of the string. As a result, strain energy is stored and then converted into kinetic energy, thereby increasing the velocity.
