Ring frames, stringers and skin panels are the main parts of aircraft fuselage structure. Circumferential joint is formed by joining skin panels in circumferential direction using doubler plates and adhesive bonding. In this paper finite element (FE) modeling of circumferential butt joint of fuselage structure using commercial FEA software (ANSYS) is presented. The FE model is validated using a benchmark and then fracture mechanics results are graphically presented and discussed.
