Cratering flow fields - Implications for the excavation and transient expansion stages of crater formation

S. K. Croft

Abstract

A Maxwell Z-model cratering flow field originating at non-zero depths-of-burst has been used to calculate theoretical depths and volumes of excavation, hinge radii, ejection angles, and transient structural rim uplifts for comparison with experimental and field data from impact and explosion craters.
