Simulation studies on ring upsetting using the ABAQUS software

In this paper, a simulation and an experimental analysis of upsetting a cold ring placed between two rigid plates were conducted. When designing a new process, it is preferable to carry out the simulation studies using FEM, which allow for the prediction of the course and proper selection of process conditions. Due to the complexity of phenomena that occur during plastic formation, it is essential to have a good description of contact phenomena and properties of material in the plastic state. The computer simulation was performed for a specific material – a thick plate of hot-rolled carbon steel with fixed initial dimensions of rings and different values of the coefficient of friction.
