Advances and challenges on springback control for creep age forming of aluminum alloy

Liwen Zhang et al.

Summary: Creep age forming (CAF) is an advanced forming technology that combines creep deformation and age hardening processes. It has many advantages such as low residual stress, dimensional stability, good performance, and short production cycle, making it optimal for manufacturing large-scale complicated thin-walled components of high strength aluminum alloys in aviation and aerospace industries. However, a major challenge of CAF is the occurrence of springback after unloading, which affects the accuracy of shaping components.

Investigation of stress effect on creep, precipitation and dislocation evolution of Al-Li alloy during creep age forming

Xi Wang et al.

Summary: The creep-ageing behavior of a 2xxx series 3rd generation Al-Li alloy in T8 state was experimentally investigated under different stresses, showing significant differences in creep strain with increasing stress levels. The dominant deformation mechanism shifted from diffusion creep to dislocation creep at higher stresses, revealing a strong stress dependent characteristic in creep deformation and evolution of dislocation density and precipitate size during creep-ageing.

Springback prediction model and its compensation method for the variable curvature metal tube bending forming

Shuyou Zhang et al.

Summary: This paper proposes a springback prediction model for variable curvature tube, which can calculate the curvature radius of any point on the tube central axis curve and establish a functional relationship between the springback of the tube and its original parameter equation. The model can obtain the bending compensation amount for the variable curvature tube, which is used to improve bending forming precision. Experimental results showed that the proposed method was effective in predicting springback for variable curvature MT.

Analytical springback assessment in flexible stretch bending of complex shapes

J. Ma et al.

Summary: Stretch bending is commonly used for fabricating complex profiles, but controlling springback remains a challenge. This study introduces a novel stretching-controlled bending process and develops a Full Moment analytical model for accurate springback assessment. Experimental validation demonstrates high capability for controlling springback and dimensional accuracy.

On pure bending in non-linear elasticity: A circular closed-form 2D solution for semi-linear orthotropic material

Gordan Jelenic

Summary: This study revisited the large-deformation pure bending of a straight beam, extending it to orthotropic linear-elastic materials and plane stress situations. The solution for orthotropic linear-elastic materials still exists in closed form, providing a benchmark reference for numerical methods in non-linear elasticity. Through-the-thickness stresses develop in a hyperbolic cosine form, with the magnitude depending on a measure of orthotropy, while longitudinal stresses change in a hyperbolic sine form.

Modelling of Springback in Tube Bending: A Generalized Analytical Approach

J. Ma et al.

Summary: This research presents a generalized analytical solution for springback in tube bending, enabling accurate and efficient analysis of springback for bending of general tubular materials, in particular, for the tubes with tension-compression asymmetry. By taking the rotary draw bending of high-strength titanium tubes as a case study, the developed analytical model was carefully evaluated, showing its good efficiency for springback prediction - particularly for the large-angle (>= 90 deg.) forming cases.
