Numerical Mathematical Simulation of Penetration of Indenters of Different Shapes During Strengthening Machine Parts via Local Loading of Deformation Zone

摘要

Numerical mathematical simulation of the strengthening combined local loading of the deformation zone in the process of penetration of indenters of different shapes into the piece body was considered. The simulation results were presented in the form of the pattern corresponding to the Odkvist parameter change depending on the type of the tool and the depth (force) of its penetration into the piece body. Based on the analysis of numerical mathematical simulation data, practical recommendations have been formulated pertinent to the selection of the indenter shape for the processes of gradient strengthening of machine parts in the conditions of combined local loading of the deformation zone.
