3D rigid-viscoplastic FEM simulation of forging process of a compressor stator blade;

In this paper,the process of superplastic bulging with symmetric die,which is chosen to be a conical one with arbitry slant angle(including cylinder),is investigated by large deformation rigid-viscoplastic finite element simulation,and the cavity effect is considered by the modification of the thickness of matrix and R-T medel.

Numerical simulation based on 3D thermal coupling rigid-viscoplastic finite element technology had been carried out on the forging process of titanium-alloyed turbine blades,which is validated with actual forging technological experiments.

3D rigid-viscoplastic FEM has been applied to the RR upsetting process of heavy crankshaft with analysis of the influence of variety of temperature field on its plastic deformation and forged dimension.
