Abstract Scope Deformation behavior of a 5000 series aluminum alloy sheet under biaxial tension is precisely measured for linear stress paths in the first quadrant of stress space, using servo-controlled biaxial tensile tests with cruciform specimens (ISO 16842). Successive contours of plastic work in stress space and the directions of plastic strain rates are precisely measured and compared with those calculated using the Yld2004-18p yield functions. Genetic algorithm is used to determine proper combination of the anisotropic parameters and exponent of these yield functions so that the difference between the predicted and measured data is minimized. Moreover, finite element analysis (FEA) of hole expansion forming is performed using the yield functions and compared with experimental data. The calculated thickness distribution in the vicinity of the hole edge is qualitatively in agreement with the measurement. The cause of the discrepancy between the FEA and experiment is discussed.
