Cold and Hot Forging: Fundamentals and Applications
This chapter introduces an inverse analysis technique for the accurate determination of the input data for finite element method (FEM) simulation to determine material parameters in the flow stress model and the friction at the tool/workpiece interface. The discussion starts with an overview of direct and inverse problems, describing the procedure for parameter identification and providing a summary of past studies on inverse analysis. The processes involved in flow stress determination and also in the simultaneous determination of flow stress and friction are discussed, outlining the variables involved, the calculating procedure, as well as the advantages of the inverse analysis process by FEM. The chapter end with an example showing the determination and verification of flow stress and friction by inverse analysis.
