crumple zone 
noun
A part of a motor vehicle, especially the extreme front and rear, designed to crumple easily in a crash and absorb the main force of an impact.Alternatively, the crumple zone in the larger vehicle can be designed to crush at the same rate and degree as that of a lighter car, so that they absorb the same amount of energy....
- Since you don't have a crumple zone, the material has to take in all the force/energy and transfer it.
- What we have done in the front is we have a structure that is very similar to a car structure, which means that it has a crumple zone.
