The Challenge of Crashworthiness for Composites Cars By Giuseppe Resta on Aug It doesn’t seem so long ago that passenger safety and vehicle crashworthiness were the battleground where automakers differentiated their products. Crashworthiness is the science of minimizing the risk of serious injuries and fatalities in motor vehicle colli-sions.

There are five basic principles involved in reducing injury producing hazards following a motor vehicle accident: To provide adequate crashworthiness in a motor vehicle accident, the vehicle’s safety systems must work together. This paper presents an automated algorithm for the design of vehicle structures for crashworthiness based on the analyses of the structural crash mode (CM).
