3D-Computer Modelling of Contact Interaction between Spherical Indenter and Elastic-Plastic Body

Abstract:

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.
