Article Preview

The finite element model of a symmetric tapered attachment lug is built by using the finite element software ANSYS, a cosine pin-bearing pressure distribution is applied on the surface of the pin-hole as a boundary condition. The stress intensity factor (SIF) expression for a single through-the-thickness crack in a symmetric attachment lug subjected to an oblique pin-load less than 45 degrees is determined by studying on the effect of the dimensionless crack length (a/R1),the ratio of outer radius to inside radius (R2/R1), the inside radius (R1), the tapered angle (β) of lug and the load degree (α) on SIF value. The paper can be helpful in assessing and designing damage tolerant attachment lugs.
