Displacement values of BIW parts from its position during crash.
Von misses stress occurring in the BIW during the crash.
According to the forces observed through the graphs above, the first peak force is achieved in rails, shotgun and A-pillar respectively. This shows the flow of forces through the BIW. Rails and shotgun are designed to crumble downwards hence absorbing maximum force from the impact. Bumpers, rails and shotgun absorb the maximum amount of energy in a frontal crash, hence, their importance in safety regulations is the highest.
