Abstract

Metal forming processes and formed components can be enhanced by stress superposition. Stress superposition is defined here as adding stresses on an existing (primary) forming process acting simultaneously with the core stress state. An extensive analysis of existing applications leads to a systematic classification of current stress superposition methods. The mechanisms of stress superposition and the modelling are provided. Achievable improvements in the reduction of forming force, increase in formability, and tailoring physical properties are presented. The limits of stress superposition and future opportunities of designing new forming processes through utilization of stress superposition are proposed. [ABSTRACT FROM AUTHOR]
