This paper considers the problem of cone indentation in the surface of elastic-plastic body. The paper presents the relevance of the research. Are shown design scheme and finite-element model.Made verification of the contact algorithm.Qualitative and quantitative agreement between the numerical and theoretical solutions have allowed to conclude on the adequacy of the used contact algorithm and its applicability to solve the problem.Calculations were made for various combinations of material properties.Are some of the graphics profile geometry beading, which remains on the surface of the elastic-plastic body after removal of the load with a conical indenter.Conducted approximation of the data obtained and the four-parameter function describing the profile of the beading.
