Study of Cold Rotary Forming by Using Rigid-Plastic Finite Element Method

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.
