The book gives a synthetic presentation of the research performed in the field of sheet metal forming simulation over the course of more than twenty years by the members of three teams: the Research Centre on Sheet Metal Forming – CERTETA (Technical University of Cluj-Napoca, Romania); AUTOFORM company from Zürich, Switzerland and VOLVO automotive company from Sweden.
The first chapter reminds some fundamental topics of the theory of plasticity. A more extended chapter is devoted to the presentation of the phenomenological yield criteria, emphasizing the formulations proposed by the CERTETA team (BBC models). A section of this chapter has been dedicated to the modeling of the Bauschinger effect, especially the AutoForm model. The sheet metal formability is discussed in a separate chapter. After presenting the methods used for the formability assessment, the discussion focuses on the forming limit curves. In this context, the authors emphasize their contributions to the mathematical modeling of forming limit curves. The role of simulation in the process planning, part feasibility and quality, process validation and robustness are presented based on the AUTOFORM solutions. The performances of the material models are proved by the numerical simulation of various sheet metal forming processes: bulge and stretch forming, deep-drawing and forming of complex parts. Special sections have been devoted to the robust design of sheet metal forming processes, to the springback analysis and Computer Aided Springback Compensation.
The book is useful for the students, doctoral fellows, researchers and engineers who are mainly interested in the mechanical modeling and numerical simulation of sheet metal forming processes.
