title = "Numerical analysis of superplastic bulging process of tial sheet",
abstract = "The superplastic bulging process of TiAl sheet was simulated by coupling superplasticconstitutive equation to finite element model. Based on this model, the effect of coefficient of frictionbetween the sheet and mold and the size of the mold fillet on the superplastic bulging (SPB)performance of TiAl alloys sheet were studied by analyzing the evolution of equivalent plastic strainand thickness distribution in the sheet. The results showed that friction was the dominant factor of thenonuniform thickness of the sheet, while higher friction and smaller radius of mold fillet inhibited theover-thinning of sheet on the entry of mold cavity. The simulation results were in good agreementwith the experimental results. Therefore, the present model could be used for optimizing the selctionof the deformation parameters and the design of the structures.",
