The article presents the results of the study of contact interaction of cylindrical, conical and roller-shaped punches with concrete. The stress-strain state of the material is assessed during penetration. The paper discusses how the angle of tapering of a simple punch shape affects the contact strength of the material. There are some hypotheses in the paper that describe the nature of the interaction of simple punch shapes with the material, there is a high convergence of the results with the main provisions of the mentioned hypotheses. In particular, it is found that the contact stresses in the area of contact of a punch with the material in areas significantly exceeding the strength limit of concrete can be characterized by the ratio of the strained volume of the material to the volume of the pressure bulb of the material. Its size is determined by the properties of the material.
