.... 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...

... metal parts can be classified into three categories; wrinkling and fracture during the forming stage, and springback during the stage of tool removal. Great efforts have been concentrated mainly in predicting and improving the instability defects such as wrinkling and fracture. However, springback has...
