Numerical Simulation and Deformation Research for Cold Enlarging Tube Diameter
This paper presented how to build finite element model based on UG NX, and simulated the cold expanding process by DEFORM software. The deformation, distribution and development trend of velocity, equivalent stress, equivalent strain and equivalent strain rate were predicted. The punch’s load-time variation curves in X, Y and Z direction were also obtained.
