BLOW AND PENETRATION OF CYLINDRICAL BODIES IN SOFT GROUND
Numerical methods solve problems of normal blow and penetrating of cylindrical bodies in the soft ground. The system of the nonlinear equations describing dynamics of interacting mediums is grounded on parities of mechanics of continuous mediums and the model of soft ground dynamics by S. S. Grigoryan. Integration of the equations is made on the basis of S. K. Godunov''s modified scheme realized in the application package «Dinamika-2». The feature of a method is the application of ejlero-lagranzheva approach to the description of mediums movement with the use of any mobile separate grids. Depths and the overloads tested by striker with various headings at penetrating in soft ground are defined. The received results are compared to the experimental data and known analytical and empirical decisions.
