This paper on predictive fatigue failure analysis of an aircraft’s rear fuselage discusses the ultimate strength and the sudden occurrence of fatigue failure. Therefore, predicting the failure and preventing it before it occurs would be an excellent strategy to design against fatigue. In this paper, the crack propagation rate in linear fracture mechanics will be used to calculate fatigue life, and simulation in solidworks will be compared with the analytical solution. The suggested fatigue life for the fuselage would be the one with the lowest fatigue life among the two methods.
