Abstract: In the present study, stress and fracture mechanics analysis for a pin-loaded straight attachment lug were carried out using the Boundary Element Method. The effects of geometric parameters such as orientation of loading and outer-to-inner were investigated. The location of the highest stress concentration factor was determined by evaluating the stress distribution on the inner radius of the lug. Cracks were modeled at those critical locations and Stress Intensity Factors were obtained using the BEM. The analysis showed that the direction of loading and the outer-to-inner radius ratio have significant effects on the stress concentration factors and stress intensity factors, thus influencing the crack propagation path of the pin-loaded lug.
