Origami has inspired a wide range of engineering applications, from deployable systems to structures with enhanced mechanical performance. In this context, Yoshimura patterns, commonly observed during the axial crushing of circular thin-walled tubes, offer a promising basis for designing energy-absorbing components. This paper presents an experimental investigation into how the geometric parameters of a Yoshimura cylindrical tube influence its axial crushing response. The parameters examined include the in-plane panel angle and the number of sides around the circumference. The results indicate that these geometric features significantly affect both the peak load and the energy absorbed during collapse. Higher in-plane angles lead to increased peak loads and stiffness within the tested range, while tubes with fewer sides, particularly three, exhibit a more gradual post-peak load reduction. Conversely, tubes with a larger number of sides show a sharper drop in load after the peak. These findings demonstrate that the crushing mechanics of Yoshimura tubes can be tailored to specific energy-absorption requirements through appropriate geometric design.
