Thin-walled tubes with origami patterns are popular design for the energy observing devices. However, less study has been done when they subjected to cracks. In this work, the origami square tube with different height to wall thickness ratio are first studied to investigate the collapse modes and deformation mode. Further more, stress concentration areas are identified by numerical simulations. Finally, horizontal and vertical crack was implemented in one of the side in order to study the effect on the deformation mode.
