摘要：The numerical results of superplastic punchless deep drawing of the Ti-6Al-4V titanium alloy were presentedin this paper. The material behavior subjected to the forming process was characterized by deformation-micro-structure constitutive equations including the grain growth. Superplastic stress-strain characteristics used in thenumerical simulations were computed with the application of authorial program. The explicit integration schemeis used in solving differential equations. The numerical simulations of the super-elastic deep drawing were madewith finite element method analysis. The von Mises stress distribution in the blow-forming process was obtained.The possible faults of extrusions caused by the improper load history as well as unsuitable pressure were alsopresented in this paper. The numerical simulations included in this research allow for the proper choice of materialand drawing parameters which can help to optimize the superplastic forming process.
