Abstract

An efficient numerical method has been developed and programmed to predict springback in creep age-forming (CAF) of aluminium shell components. Physically based unified creep-ageing constitutive equations determined for AA7010 at 150 °C are used to evaluate age-hardening and creep deformation in CAF processes. The studies are mainly concentrated on the pure bending of aluminium plates. Effects of plate thickness, single and double curvature bending, ageing time and stress relaxation features on springback are investigated. It is shown that the proposed algorithm can predict springback accurately and gives a relationship between geometrical data and springback.
