Abstract:For the long-serving aircraft, the holes in the overlap of the aircraft skin will change from circular holes to elliptical holes under the action of load. It is of great significance to calculate and analyse the stress intensity factor of the multi-elliptical hole-edge crack for the fracture mechanics analysis. This paper used the analytical calculation methods of finite truncation method and residue method. Both methods are based on the theory of complex function and combined with the approximate superpositio… Show more
