This is the only way to reduce the kinetic energy of an impact and minimize the acceleration forces on the occupants and the rest of the vehicle.
- modern joining methods require de-consolidated points, which allow the joining of identical or different materials. Often, for example, crimping or riveting joints have to be used, which presuppose deformable areas in the component.
