Car safety becomes an issue almost immediately after the invention of the automobile. To protect occupants from a direct impact, the passenger compartment and the structure of the vehicle should keep its shape in a crash. Side-impact collisions are the most critical crash scenarios and a second leading cause of death and injury of people in the traffic accidents across the world. Carís side body structures like side impact beams of doors and double skin pillars were developed to reduce the impact and depth of side body structures deformation into the passenger compartment in side impact crashes. Assessing the effectiveness of side impact beams are significant for reducing occupant fatalities and serious injuries. By using the relation between maximum absorbed impact energy and minimum structural weight the new techniques was developed and also crashworthiness performance was improved related with material optimization and thickness.
