Abstract : This report presents a study of various phenomena which are generated in rock like media by a nuclear surface burst. Three principal regions of interest are considered: (1) an extreme close-in region in the neighborhood of Ground Zero in which the medium is represented by a hydrodynamic model; (2) a transition region in which the medium is represented by an inelastic solid material model which exhibits energy dissipation; and (3) a nearly elastic region in which inelastic energy dissipation is assumed very small and the material acts elastically. Computer codes have been developed for each of the regions. Numerical results are presented for the case of a two megaton surface burst on a tuff medium. The computed values from Region (1) are used as input parameters for the continuation of the problem into Regions (2) and (3). (Author)
