The crater radius and depth depend on the material physical parameters like the Young's modulus and the Poisson's ratio.

The way it works is to model the crater as a hemi-spheroid, then find the mass of the ejecta, and then to calculate the energy required to lift the ejecta to an altitude equal to the crater radius. This method produces a minimalistic number, and is intended as a sanity check on the other methods:
