Abstract: In this project, investigation of stress concentration factor is carried out. Some specimens with shoulder fillets and circular holes are involved with the machining process according to the dimensions. An axial force is applied to the member; it creates a complex stress distribution within a localized region of the point of load application. The complex distribution arises when there are concentrated loading and changes of the member’s cross sectional area. Thus, if there is a change in shapes or loading in member, the stress distributions also will be change. This study investigated the stress concentration of different materials with different shapes. The laboratory experiments for the strain measurement were conducted and the maximum stress, average stress and stress concentration factor (K) were determined. The stress concentration factor (K) value is compared between the theoretical values found in standard K value chart with the experimental results. Also with the help of computational method, the software analysis was followed up to compare among the overall K values in these three methods. In the end, some recommendations are made for the future investigation.
