Next about the performance requirements.
Well here I'm speaking more in terms of LS dyna as that is my tool of experience.
Global energy, Understand how the energy curves vary for each load case. For example how would the energy curve look for a quasi static load like SBA and how it would vary for a dynamic case like pendulum crash. Why does it differ?
Learn to draw a schematic diagram of the vehicle in terms of the load path.
For example from the bumper beam, towards the crush cans and then the rails etc, or for the same load case (full frontal) if we look at it from a slighter higher position, the load path is from the radiator, then the shotgun, hinge pillars etc.
If the frontal impact starts of with a force of 200 kN how does it get transferred towards the end of the vehicle.
