This book was released on 1974 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Cratering Facility was designed and constructed for the purpose of performing laboratory-scale, high-explosive cratering experiments. Fifty-five events were conducted in which centrally initiated, spherical, lead-azide charges were detonated in dry Ottawa sand. Charge configurations for these events ranged from 5-charge-radii height of burst to 15-charge-radii depth of burst. The techniques required to maintain a well characterized 'standard' sandbed were developed and employed for two series of experiments. The 'standard' sandbed was chosen to be that with an in-situ density of 1.801 gm/cc. The main or Overall Series of experiments was conducted in the 'standard' sandbed to determine the relationship between apparent crater size and charge configurations. Realistic levels of reproducibility for various cratering experiments, in terms of apparent crater dimensions, were determined by conducting a Benchmark Series of experiments.

Available in PDF, EPUB and Kindle. Book excerpt: Aspects of cratering phenomenology are considered along with material properties and shock effects, theoretical cratering mechanics, ejecta, and problems of scaling. Attention is given to the application of high explosion cratering data to planetary problems, cratering mechanisms observed in laboratory-scale high-explosive experiments, nuclear cratering experiments, complex craters in alluvium, terrestrial impact structures, the Ries impact crater, buried impact craters in the Williston basin and the adjacent area, crater morphometry from bistatic radar, a Fourier analysis of planimetric lunar crater shape, a stratigraphic model for Bessel Crater and southern Mare Serenitatis, a nested-crater model of lunar ringed basins, Martian fresh crater morphology and morphometry, the distribution and emplacement of ejecta around Martian impact craters, the nature of the present interplanetary crater-forming projectiles, cratering mechanics and future Martian exploration, the response of rocks to large stresses, the dynamical implications of the petrology and distribution of impact melt rocks, and a review and comparison of hypervelocity impact and explosion cratering calculations.
