Description:
We have continued our shock physics code calculation studies of DART-like impact events. This includes comparisons of iSALE and SPH code calculations, using a range of strength and structural properties. The effect of porosity was studied in detail by applying different crushcurves, representing materials with varying crushing strength. The crushcurve was found to have a large influence on the outcome, in particular the ejecta properties and momentum transfer.
