In this project, a rigid plastic Finite Element Method (FEM) simulator was developed for simulating the plastic flow material in rotary forming. The simulation result was able to predict the cup height of the final product up to an accuracy of 80% and the localized deformation which leads to failure in the deformation process. The workability of the aluminum disc was also studied to understand the material flow behavior under incremental bending and flow forming by utilizing a lathe machine.

In this paper, single action die and double action die hot forging problems are analyzed by a combined FEM, which consists of the volumetrically elastic and deviatorically rigid-plastic FEM and the heat transfer FEM. The volumetrically elastic and deviatorically rigid-plastic FEM has some merits in comparison with the conventional rigid-plastic FEMs. Differences of calculated results for the two forging processes can be clearly seen in this paper. It is also verified that these calculated results are similar to those of the conventional rigid-plastic FEM in comparison with analyses of the same numerical examples by the penalty rigid-plastic FEM.
