In this study, theoretical modelling and finite element simulations were performed to reveal
the forming mechanics of involute components based on a 3D free bending process. During …

In order to investigate the wrinkling behavior of thin-walled tubes under complex stress
states, a dedicated experimental setup was designed and manufactured. In this …

Finite element method and bending experiments were carried out to survey the influence of
bending radius on forming quality of H62 brass tubes in free bending process, which are …

The smaller the relative bending radius of the bent tube, the more difficult the tube blank is to
be bent. In this paper, the push-bending process for the aluminum tube with a relative …

Abstract Thin-walled (D/t> 30; D, initial outer diameter; t, initial wall thickness) bent tubes
with large diameter (D> 100 mm) and small bending radius (R/D< 3; R, centerline radius) …

The cold push forming method of 1D bending radius (R/D= 1) with small diameter and small
bending radius using low-melting-point alloy as filling medium is studied in this paper. The …

The averaged value of the Strain Energy Density (SED) over a well-defined volume is used
to assess the critical fracture load of notched components made of Functionally Graded …

The elbow push-bending process involves pushing a tube between a die and a mandrel to
bend a tubular blank into an elbow shape. In this study, the yield was improved by …

It is important for the thin-walled tube with relative bending radius of 1 to be bent with
mandrel in order to avoid the defects such as wrinkling and cross-section distortion. In this …

In this paper, the response surface methodology (RSM) and finite element (FE) simulation
were applied to optimize the push-bending process parameters of the thin-walled tube with …
