Abstract
The problem of penetrating an absolutely rigid indenter in the form of a round cone into a weighted rock (an axisymmetric plasticity problem) is being solved. Limiting load is determined, depending on the internal friction angle of rock, adhesion, angular opening at the top of cone, rock weight. The dependence of load on the above parameters is given.
