Finally, it is useful to compute the total energy dissipated in the collision. It is called the
crush energy dissipation (CED) because most of the dissipated energy goes into the defor-
mation of the vehicles. We may then compare the CED to the results of EDCRASH or other
computer programs that calculate the energy based on crush. e computer program,
EDCRASH, computes this quantity based on the class of the vehicles and the damage to
the vehicles. Please refer to the EDCRASH program for more details. Here, the CED is
computed by taking the dierence between the total initial and nal kinetic energies. us, ...
