Notes:
The paper presents numerical and experimental results of continued studies of curvedfatigue crack growth in arbitrarily pre-cracked isotropic sheets under biaxial proportional planeloading. The predictor-corrector method (PCM) was extended in order to analyse the growth ofmultiple crack systems. As a result, the program PCCS-2D was written to run within ANSYS withoutany user interaction. In order to check the accuracy and efficiency of the method biaxial crackgrowth simulations were carried out for a fracture mechanics cruciform specimen. The results arecompared with experimental findings obtained by specimens made of 6061 aluminium alloy inT651 condition using a 250kN biaxial servohydraulic testing machine. From the numerical and experimentalresults, we conclude, that the proposed predictor-corrector method can be used in curvedcrack growth simulation also under biaxial proportional loading conditions
