Numerical Modeling of Crater Formation by Meteorite Impact and Nuclear Explosion
The NOBEL code for modeling compressible fluid dynamics is used to model the formation of the Arizona meteor crater by a 50 meter diameter iron asteroid impacting basalt at 12 kilometers/second. The code is also used to model the crater generated by the SEDAN 104 kiloton nuclear explosion. To reproduce the observed crater sizes it is necessary to include the properties of pulverized rock created by the shocking and rarefaction of the rock.
