New Developments in Superplastic Forming Simulation and Industrial Applications

Article Preview

Abstract:

In this paper, the authors presented the material models and numerical algorithms adopted in PAMSTAMP 2G for superplastic forming simulation. The improvements in strain rate control, automatic stop criteria, velocity scaling and shell element formulation to include normal stress can improve the accuracy and efficiency of superplastic forming simulation.
