Crack growth is investigated numerically in a cruciform specimen with an inclined center crack subjected to biaxial fatigue loading. The mixed-mode fatigue crack growth was examined using a parametric study both on the biaxial stress ratio and the initial crack angle. A fatigue crack growth code for two-dimensional problems was developed to investigate the mixed-mode behavior of fatigue crack growth under biaxial loading. The effects of initial crack angle and the biaxial stress ratio on the specimen fatigue life are explored using finite element analysis and the results are discussed.
