Abstract The most common form of damage in aircraft structures is fatigue damage. Accurate detection of fatigue
crack tip is the cornerstone for prediction of crack propagation path and the basis for calculation of residual
strength and stiffness. It is of great significance to improve structural fatigue resistance design. When
simulating the crack growth problem based on the traditional method, the crack tip needs to be re-meshed
so that resulting in low calculation efficiency. The expansion of fatigue cracks has a complex shape, for
example, the fatigue crack damage on the aircraft skin often shows a curved shape. The current traditional… More >
