An overview of projectile penetration into geological materials, with emphasis on rocks
- Lawrence Livermore National Lab., CA (USA)
An extensive study was performed of the experimental and analytical aspects of projectile penetration in rocks and soils. The experimental data base is much larger for soils than it is for rocks, in which few instrumented penetration tests have been performed. To extrapolate experimental results, several methods of analysis and prediction have been proposed: empirical approaches, such as those of Sandia National Laboratories and the Army's Waterways Experiment Station, analytical methods, such as cavity expansion theories and the differential area force law, and numerical modeling by a variety of techniques, i.e., finite differences, finite elements, and discrete elements. This paper contains a comprehensive summary of the features of the various computer programs used for penetration modeling, in many materials and at various speeds, over the past 20 years. 144 refs., 9 figs., 3 tabs.
