Purpose: FEA analyses are frequently faced with modeling situations where field surface and changing contact cannot be assumed ignored. Design/methodology/approach: The effect of stress in machine elements due to friction between working machine parts has to be considered for analyzing the machine component with ANSYS software package. The interaction between the hole surface and pin was modeled with contact elements. In this study, examination of stress in pin-pin hole connections was carried out by using ANSYS program. Findings: The connection in pin-pin hole plates occurs between surface of pin hole in plate and side surfaces of pin. Stresses in contact surface of selected machine elements were investigated. Three different materials such as steel, aluminium and structure steel were analyzed under three different rates of cylindrical plate radius r and length of hexagonal pin 2h (r/h = 2.5, 5 and 7.5). Stress analysis was carried out in x, y and z axises. Research limitations/implications: Among the stress forms, in general, the maximum stress for all the three types of materials examined here was found to be occurring as the von Mises stress. Originality/value: The comparison of the maximum normal stress, maximum shear stress and von Misses stress were determined.
