Abstract
An apparatus has a tubular body with a channel and a number of stiffeners. The number of stiffeners allows the tubular body to absorb additional mechanical energy through axial compression. Additionally, the number of stiffeners is located on a number of locations for the tubular body. The apparatus also has a plurality of hinges located in part between the number of locations of the number of stiffeners for the tubular body, and also located between end flanges at the end of the tubular body and a stiffener. The number of hinges further define deformable regions. At least one deformable region of the plurality of deformable regions is configured to expand away from the channel in response to the tubular body being compressed in the axial direction.
