Abstract: 3-D rigid plastic FEM(Finite Element Method) is adopted to simulate the extruding-bulging process of tee tubes. Deformed mesh and velocity field in different stages are obtained, and strain-rate and stress distributions are obtained at the same time. The deformation and flowing laws of tubular blank in extruding-bulging process of tee tubes are revealed, which provide scientific and reliable basis for correctly designing technological scheme and rationally selecting parameters.
