A Solution for the Prediction of Springback in Age-Forming Strip

Article Preview

Abstract:

Creep age forming (CAF) is an effective process to manufacture aircraft panels with better performance including improved strength and toughness, lower weight and increased resistance to fatigue and corrosion. Due to restrictions of aging cycle to create the desired property, springback in CAF is larger than other forming processes. That makes its prediction one of the key technologies in CAF. A solution is developed to predict springback in CAF of aluminium components. The studies are mainly concentrated on the pure bending of aluminium strips. Comparisons of predictions with experimental data yield agreement. Effects of T-beam’s structural factors, like width, skin thickness, rib width and transitional radius on springback are investigated. And a relationship between geometrical data and springback is given by the proposed algorithm.
