.... During springback, the joint is freely stressed. During extraction, the joint is pulled to its limit, activating local sliding. Based on these observations, we develop an analytical model capable of describing the bonding behaviour without using FEM. Findings The elasticity of the material...

...Radha Krishna Lal; Vikas Kumar Choubey; J.P. Dwivedi; V.P. Singh Purpose The purpose of this paper is to deal with the springback problems of channel cross-section bars of linear and non-linear work-hardening materials under torsional loading. Using the deformation theory of plasticity...

... are compared with each other from the viewpoint of both the forming stage and the springback stage. The S‐rail benchmark problem of NUMISHEET’96 is chosen as a numerical example since the problem is very well documented and, furthermore, the average values of the experimental results are available in order...
