A containment vessel (10) or retaining projected high energy material fragments produced during the catastrophic failure of a high energy rotary mechanism, such as a composite flywheel (20), includes a continuous outer ring (30) and a plurality of inner shaped elements (40) that produce an inner ring layer. The outer ring (30) is approximately circular in shape and is designed to be unyielding during a flywheel failure. The inner shaped elements (40) are juxtapositioned axially along the inner periphery of the outer ring (30) and are configured and positioned to produce hollow cells (60). These shaped inner elements (40) are adapted of a material and are configured and positioned in such a way as to possess sufficient ductility so that the elements adequately flatten through non-destructive plastic deformation and contain the high energy material fragments (50) of a failed flywheel (20). The hollow cells (60) formed by the configuration and positioning of the shaped elements (40), plastically deform (or bend) at a rate fast enough to absorb the high level of energy from the impact over a significantly extended time interval and thus prevent the shaped elements (40) from experiencing ultimate tensile failure (rupture) or localized compression failure (buckling).
