Experimental and Numerical Analysis of Circular Tube Systems Under Quasi-Static and Dynamic Loading

In the study of impact attenuation devices, rings/tubes have received a large amount of research due to their adaptability, i.e. they are low in cost and are readily available for selection in the design process. They also exhibit desirable force-deflection responses which is important in the design of energy absorbing devices. The function of such a device is to bring a moving mass to a controlled stop and ideally cause the occupant ride down deceleration to be within acceptable limits so as to avoid injuries or to protect delicate structures.
