Abstract
The presence of cracks at more than one fastener hole in a row of fastener holes limits the safe use of a component more than if cracks exist at the edge of one hole only, since the stress intensity factor is greater, the crack growth-rate is faster, and the fatigue lifetime is less. The limitations can be made less severe if the component is made with alternate fastener holes in the row displaced to form another parallel row. The compounding method of evaluating stress intensity factors is used to calculate the stress intensity factor as a function of crack length, hole spacing, and row separation. Fatigue growth-rates are calculated for the particular case of a periodic array of holes with two cracks of equal length at each hole.
