For accurate illustration of complex plasticity and fracture behaviors of a QP980 sheets, some advanced models were proposed for plasticity deformation and fracture prediction under various loading conditions of shear, uniaxial tension, plane strain tension and equibiaxial tension. However, experiments are not perfect for different loading conditions especially at large plastic deformation. To couple the imperfection of each tests during model calibration, an inverse engineering approach is developed to calibrate plasticity and fracture models by directly comparing experimental results with numerical simulations. The calibrated plasticity and fracture models by the inverse engineering approach are compared with experimental results. The comparison demonstrates that the inverse engineering approach dramatically improves the accuracy of the advanced constitutive models in the prediction of plastic deformation and the onset of fracture.
