The initiation and propagation of fatigue cracks in bonded sheets are investigated. Two sheets of 2024 T346 aluminum alloy are bonded together either with CC15 or Epoxy adhesive and a center notch is created in one of them. The bonded second sheet tends to reduce the stress intensity factor at the tip of the notch in the first sheet, thereby retarding both crack initiation and propagation. The experiment is compared with calculated reductions in stress intensity factor and the crack growth results show reasonable agreement.
