Computer simulation of contact interaction between a spherical indenter and soil surface was performed by the means of ANSYS software. It was assumed that the soil was elastically-plastically deformed in accordance with the model of Drucker-Prager. The case of indenter inserting and its contemporaneous displacement along the contact surface was considered. The results obtained by different material models show that the maximal stresses are reduced by 50% and more for the Drucker-Prager model in comparison with the results for the elastic model. The influence of horizontal movement-vertical movement ratio for the indenter on the stresses in the soil was analyzed.

Computer simulation of contact interaction between a spherical indenter and soil surface was performed by the means of ANSYS software. It was assumed that the soil was deformed elastically-plastically in accordance with the model Drucker-Prager. It was carried out the analysis of the influence of the model base physical parameters on the stress-strain state of the contacting bodies. The comparison of the calculated by linear elastic model and Drucker-Prager model stresses values for the soil showed that for the case of the elastic-plastic model are three times less than for the case of the elastic model.
