EES
Definition
Speed corresponding to an assigned deformation energy under a defined mass and convention. State the deformation-energy model and inputs used. It is not automatically the vehicle’s pre-impact or closing speed.
- Context
- Vehicle reconstruction
For example, a deformation-energy equivalent speed should not be relabelled as impact speed without the additional assumptions needed for that reconstruction.
Energy partition and other losses require separate consideration.
