Abstract
An energy absorption device absorbs energy that is released upon impact between two objects in relative motion. An exceptional load applied to any of the two objects results in acceleration of one object relative to the other object. The acceleration energy is absorbed by deformation of an element or elements that are put under stress from the objects upon impact. The process of deformation includes a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt made from a cold-formed material in the direction of force generated from the acceleration.
