A HYDRODYNAMIC MODEL OF SUPERDEEP PENETRATION OF A SOLID AXISYMMETRICAL PARTICLE INTO A SEMIINFINITE METALLIC TARGET

Ten years investigation of the Super-deep penetration problem allows o ne to understand the main features of the effect and prepare the found ation for a model that can describe the process. The paper is devoted to the creation of such a model taking account of real conditions of s uper-deep penetration process, such as an intensive pressure field whi ch is generated in the target by the flux of powder particles accelera ted by a special explosive accelerator. Accurate investigation of the problem allowed one to obtain a precise solution of the problem, at le ast for the cases of constant and time-dependent pressures. (C) 1997 E lsevier Science Ltd.
