In this study, experimental and numerical analysis of pearlitic transformation plasticity were performed in a three-point bending loading system. First the experiments were performed in bending and tensile-compressive loading systems with the same austenitization condition. The obtained pearlitic transformation plasticity coefficient for S45C steel was different for the each loading system. Therefore a new constitutive equation which called Drucker-Prager model was proposed to consider the relationship between tensile and compressive experimental results. This new model shows the dependence of hydrostatic stress. To evaluate the validity of this model, a three-point bending test was simulated with Abaqus Standard for both von Mises type and Drucker-Prager type models. The theory of phase transformation was coded in user subroutines for the each model. The simulation results (von Mises and Drucker-Prager) were compared with experimental results of tree-point bending system. The results show that the Drucker-Prager model is exactly match to the experimental results of bending test, but the results of von Mises model are different to the experimental results.
