Abstract
Stress intensity factors were obtained for radial and diametrical cracks at an offset (noncentered) loaded fastener hole. The new closed-form solution was derived by superposing and compounding several stress intensity factor solutions, including a new key stress intensity factor solution developed for cracks in a finite plate with in-plane bending loads. The accuracy of the new closed-form solutions was verified for various configurations against results found in the literature as well as finite element analysis results. Nomenclature = half crack length from tip-to-tip = length of crack i from the edge of the hole to the tip = distance between the edge and the center of the crack = edge distance of the hole = bearing to bypass stress ratio (
