Abstract Three-parameter optimisation of a wing-fuselage attachment lug was applied to its thickness, rounding radius, and radius of pin hole, using the fatigue life and mass as criteria. Numerical simulation of fatigue crack growth by finite element method (FEM) and Separating Morphing and Adaptive Remeshing Technology (SMART) was used to evaluate the number of cycles up to critical crack length. Keywords: attachment lug, finite element method, SMART, fatigue crack growth |
