Review of Materials and Process Modeling Techniques for Creep Age Forming

Abstract

The Creep Age Forming (CAF) technique has been recently developed and used to manufacture aircraft and aerospace panel components with improved mechanical properties, increased shape stability and reduced fabrication cost. Precipitation hardening, stress relaxation and creep phenomena take place synchronously in the forming process. Significant research work has been carried out over the last two decades and the applications have been expanded. This paper reviews the most recent development of materials and process modeling techniques for this new forming process. Some challenges for future modeling investigation about the novel process are also discussed.
