【 摘 要 】

In the present investigation, the growth of fatigue crack in rectangular aluminum alloy/composite plates containing an inclined surface crack was investigated. A three-dimensional finite element analysis was carried out to determine the stress intensity factors, which were used for the life estimation of three-dimensional fatigue crack growth in the plate. Moreover, the numerical results obtained were compared with the experimental results.
