I would like to design a lightening pole to be installed on the street (or in parking lots).

The height of the pole is about 1m.

I would like to calculate the impact of a car heating the pole in order to evaluate the damage to the pole (and to the car).

I know the car mass (1000-2500[kg]), and the car velocity (10-30 [km/hr]).

Therefore I can calculate the kinetic energy at impact.

I would like to know how do I calculate the damage on the pole, or what are the forces and energies it feels.

TIA, D
