     constitutive relationship equation reflects the highly non-linear relationship of flow stress as function of strain, strain rate and temperature. it is a necessary mathematical model that describes basic information of materials deformation and finite element simulation. in this paper, based on the experimental data obtained from gleeble-1500 thermal simulator, the constitutive relationship model for ti40 alloy has been developed using back propagation (bp) neural network. the predicted flow stress values were compared with the experimental values. it was found that the absolute relative error between predicted and experimental data is less than 8.0%, which shows that predicted flow stress by artificial neural network (ann) model is in good agreement with experimental results. moreover, the ann model could describe the whole deforming process better, indicating that the present model can provide a convenient and effective way to establish the constitutive relationship for ti40 alloy.
