An energy absorber is provided which can primarily be used as a replaceable energy absorbing bumper support structure. The structure includes a hollow cylinder with a stamped pattern on the cylinder wall for initiating an indented buckling pattern during crush of the cylinder. Holes in the patterned cylinder also allow for crash control of the buckling cylinder. The energy absorber is staged to provide for an increase in crush force as it progressively crashes each stage.
