Abstract
An energy absorption apparatus disposed between a pair of structures which are movable relative to each other, comprising a first operating member connected to one of the structure, a second operating member connected to the other structure, and a plastic deformation member made of a superplastic material provided between the first and second operating member and subjected to plastic deformation depending on a relative movement between the first and second operating member, and a combining layer provided between the one operating member and the plastic deformation member and having a plastic yield stress larger than the plastic deformation member, the bonding strength between the combining layer and the plastic deformation member being larger than the plasticity yield stress of the plastic deformation member.
