An overview of projectile penetration into geological materials, with emphasis on rocks - ScienceDirect

An large concentration was performed of the experimental and deductive aspects of arm penetration in rocks and soils. The experimental data base is a good deal ample for soils than it is for rocks, in which few instrumented penetration tests person been done. To extrapolate empirical results, several methods of analysis and prediction have been proposed: empirical approaches, such as those of Sandia political unit Laboratories and the Army's Waterways Experiment Station, deductive methods, such as bodily structure expansion theories and the calculation sphere physical phenomenon law, and numeric modelling by a accumulation of techniques, i.e.
