One view can be taken from applying conservation of energy. As a material deforms, it is absorbing energy and not transferring it to the vehicle nor the passengers. A brittle material will absorb less energy before shattering, letting the rest of the energy then be transferred to where you don't want it to be.
- maxerickson 10y agoIt's the energy in the passenger's body that is usually the issue. For instance, seat belts absorb the energy instead of the body flying through a window, crumple zones increase the time it takes to push the energy into a seatbelt (which decreases the force and thus the damage).
- Gibbon1 10y agoYeah this is correct. Less often talked about but actually very important, the amount of energy required to break something[1]. Also as ductile structures deform under load they tend to redistribute the load more evenly. [1] Hammer a piece of glass vs a piece of rubber.
