Determination of stress concentration factors via numerical methods: bar of circular cross section with U-shaped groove subjected to tension and bending
This paper deals with the determination of stress concentration factors using numerical methods. The cases of the bar with circular cross section and U-shaped groove subjected to tension and bending are considered. Determination of model parameters is achieved by combining the design-of-experiment, implemented in MATLAB, and Finite Element analysis, as an alternative to standard mechanical tests. The design-of experiment is used in order to set-up a variety of combinations of geometrical parameters, whereas the Finite Element analysis, performed in ABAQUS, is applied using obtained geometry variations in order to calculate corresponding stress concentration factors. MATLAB is also used for subsequent mathematical modeling in order to obtain appropriate expressions for stress concentration factors. Obtained mathematical models agree well with existing data from literature.
