Severe plastic deformation (SPD) is known to be the best method for producing bulk ultrafine-
grained and nanostructured materials with excellent properties. Different SPD methods were …

With the development of the rail transit industry, more attention has been paid to the passive
safety of rail vehicles. Structural damage is one of the main failure behaviors in a rail vehicle …

Bellows are flexible structures and widely used in different industries to accommodate the
internal pressure and deformations. This paper focuses an extensive review on analytical …

Because large plastic deformation occurs in hydroforming bellows there is a residual stress
distributing in the metal after forming, which is complex and not easy to be measured. The …

A novel buckling-induced forming method is proposed to produce metal bellows. The tube
billet is firstly treated by local heating and cooling, and the axial loading is applied on both …

The article contains the result of studies on the effects of selected geometrical parameters of
elastic bellows on their elastic properties. Bellows models were produced with using …

In this paper, an equivalent welding model is proposed that takes the tensile stress and
strain parameters of the axial weld area of the roll-welded bellows as the material properties …

Purpose Metal expansion bellows is an important flexible element used to absorb extension
or shrinkage and vibrations of the piping system used in various process applications …

Excessive thinning of wall thickness caused by the unstable deformation of metals is the
main failure mode in the manufacturing of thin-walled circular rings with complex section. A …

Because of the complex constraint effects among layers in multi-layered metallic bellows
hydroforming, the stress concentration and defects such as wrinkling and fracture may easily …
