The friction stir process (FSP), which is widely used on plate-type materials, was applied to AA5754 alloy, commonly used in engineering applications, under three different parameter settings. The effects of this process on the strength and elongation values were then evaluated. In the next stage, the material properties of the contact problem were designed using finite element-based (FEM) modeling techniques, and the effects of the changes in the strength and elongation values of the material on the contact stress and distance were determined. As a result of the examinations, it was determined that in all the changing parameters, the strength values increased compared to the initial state of the material after FSP. The elongation values may decrease or increase depending on the specific FSP parameters used. Regarding the contact stress and contact distance values, it was determined that the contact stress values increased in direct proportion to the strength of the material. It was determined that the changes in the elongation values of the material were more effective in the change of contact distances.
