Introduction According to available statistics, more than 80% of aircraft fracture accidents is caused by fatigue cracks [1]. Thus, the suppression and elimination of fatigue cracks in aircraft integral... structure. A zero-thickness cohesive zone model (CZM) was selected to simulate the adhesive layer’s fracture process, and an orthogonal simulation was designed to compare against the test results......
