Abstract

Abstract Stress concentrations typically exist around the perimeter of an opening and on attached structures, thereby resulting in a potential risk of crack initiation. Experimental and numerical methods on stress concentration distribution analysis can be applied in this study. This study reveals the differences in stress concentration distributions around various types of slots. Typical slots have been selected to discuss the influence on stress concentration distribution when the connections of flat bar and connection plate are considered. This concept is novel given the experiments conducted and finite element method (FEM) results found under complex loads. The FEM is used to compare calculated results with experimental data, and continuous plotting of numerical results can verify the outcomes. The results show the stress concentration distribution around the selected slot edge, where peak stress appears around the openings of different types of slots.
