Summary
During a forming process, the temperature of the formed part increases due to the conversion of the forming energy and the friction losses into heat. This causes the thermomechanical behaviour of the material, if the material is temperature-sensitive. The plastic deformation and the temperature change are coupled with each other, hence it is necessary to develop an effective and economic method to achieve the coupled analysis.
In this paper, the method, based on the finite element method (FEM) for the plastic deformation and the finite difference method (FDM) for the heat transfer, is found to be satisfactory for the coupled analysis. This method includes many simplified numerical procedures of the FEM and the FDM to save computational time. Both cold and hot forming processes could be calculated step by step in this way to obtain the relevant data for the design of dies and manufacturing techniques.
