ENERGY-ABSORBING STRUCTURES

摘要

An energy absorbing sheet (1) has alternating front (3) and rear (5) projections at angles between 25 to 60 degrees from the plane of the sheet. The sheet absorbs impact by plastic deformation such that the curve of stress to deformation shows a plateau for example at a level of stress which does not break bone. The sheet (1) may be made of aluminium.
