The INCh-M technique is described. The technique is realized in the software complex, destined for computation of 2D gas dynamic and elasto-plastic flows of multi-component environments with big deformations. The technique difference scheme is explicit, conservative by mass, energy and impulse, it has the second-order approximation over time and space at symmetrical positioning of particles relative to the Eulerian computational grid nodes. The results of the technique numerical study, performed on the example of a number of computations of solid target punching by penetrating elements, are presented. The computation results are compared with experimental data as well as with the results of some analogous computations performed under the OTI*HULL code.
