It is better to cru,ple since the process of crumpling absorbs some of the impact force.
to absorb the impact of the crash
You would have to crash to use them.
Crumple zone
The crumple zone crumples, absorbing some of the energy from the impact so that all of that energy doesn't crumple the passengers.
A car absorbs the energy and force of a crash in the crumple zone.
Crumple zones,Air bags,
yes, but crumple zones will reduce injury :)
This is known as the front crumple zone.
To manufacture a crumple zone in a open wheel race car we create an aluminum box riveted together. The key is that the rivets will fail in a controlled manner absorbing the energy of the crash. In a road car you start by making the passenger compartment hugely strong. Then make the crumple zone weaker in a very careful way so that as it progressively collapses it absorbs the energy of the crash.
for the case of the side of the car: if the side doors are crumple then the people in the car would be crash because there is not much space for the crumble zone to absord the force and redistribute. also, if the roof of the car is crumple, then when the car collapses , people in the car will be crash. we want the collision force to be far away from the passengers , and the way that the crumble zone work is when the car hit something, the crumble zone reduces the initial force of the crash, and they redistribute the force before it reaches the vehicle's occupants. hope this kind like give you the idea,
have crumple zones.
The concept you're referring to is known as "crumple zones." Crumple zones are designed to absorb and dissipate the energy generated during a collision by deforming in a controlled manner. This controlled crushing of specific sections of the vehicle helps to reduce the impact forces transmitted to the occupants, thereby enhancing their safety during a crash. By allowing different parts of the vehicle to crumple at varying rates, crumple zones extend the time over which the deceleration occurs, further minimizing injury risk.
