| Abstract: | A full 3-D
elastoplastic thermo-mechanical coupled FEM for large strain is applied to simulate the
hot shape rolling process from square to oval. Boundary conditions, such as heat transfer,
contact and friction, are analysed and the models about them are established. The billet
shape, temperature change and strain are obtained by calculation. The calculated results
are in agreement with those from the experiments. |
