As one kind of key components with enormous quantities and diversities, the bent tube parts
satisfy the increasing needs for lightweight and high-strength product from both materials …

The accuracy for cold-bending springback prediction is determined by the sensitivity and
accuracy of the material constitutive model. Thus, the material constitutive model is …

Springback after unloading is an issue that directly reduces the accuracy of bent tubes,
especially for Ti-alloy tubes which are of high strength and low Young's modulus. The …

Stress-relieved Ti–3Al–2.5 V bent tube in hydraulic bleeding systems improves the overall
performance of advanced aircraft and spacecraft due to its unique high specific strength …

The significant springback after the numerically controlled (NC) bending of a titanium alloy
tube has an important influence on the precision of the shape and size of the bent tube. This …

The free bending process is a promising process for forming metal pipes. It can be achieved
without the frequent replacement of mould. This process has attracted considerable attention …

With respect to wrinkling, wall thinning and cross section deformation, combined with
analytical description, the deformation behaviors of thin-walled tube NC bending with large …

Abstract Three dimensional (3D) tubes, which possess the characteristics of space saving,
lightweight and high strength, are widely used in many high-end industries such as aviation …

Springback prediction for a metal sheet during the forming process has always been a
practical problem. In this paper, based on the mixed plastic hardening rule, which …

The aim of this paper is to investigate the deformation and springback behavior of 3D tubes
under complex stress conditions. We proposed a new semi-analytical method to predict the …
