Abstract
Many of the structures and mechanical systems used have elements in contact. Determining the contact pressures and contact areas that occur after the applied load in the systems in contact is extremely important for the structure to continue its function. On the other hand, it is also known that one of the most important parameters affecting the contact pressures and contact areas of the elements in contact is the material of these elements. Although many studies have been carried out in the literature to determine the contact pressures and areas of the structures in contact with various analytical and numerical methods, it seems that no study has been conducted on how the contact pressures and contact areas will be affected by the changes in the mechanical properties of the materials in these structures. In this context, in this study, friction stir process was applied to structural steel with different parameters and the effects of this process on the strength and elongation values of the steel were examined. Afterwards, the changes in strength and elongation values were reflected in the models created with finite elements (FEM) and artificial neural networks (ANN), and the effects of material properties changing at changing loads on contact pressures and distances during contact were investigated. As a result of the investigations, it was determined that after the friction stir process, the strength value of the steel increased and the elongation values decreased compared to the base material in all parameters. Also, it has been determined that the increase in the strength of the material is extremely effective on the increase of contact pressures, and the contact areas generally decrease with the decrease in the elongation values of the material.
