Abstract: Commonly used in various industrial applications, especially in aerospace, Pin loaded lugs are common accessory for linkages in major structure. Mechanism defects in these lugs can result in catastrophic failure, hence it of interest to analyse the effects of such flaws present in lugs. Stress analysis and fracture analysis were both explored on straight pin lugs using Boundary Element Method. Geometric parameter for outer-inner radius ratios and direction of loading was varied and evaluated to determine their effects on the stress distribution on the edges of the pin-hole of the lug. Variation of effective crack length was also modelled at the critical locations found from stress analysis. Results obtained from this study presented the significance of outer-inner ratio and direction of loading on the stress concentration and stress intensity factors, relating to crack initiation and crack growth lives.
