โœฆ Synopsis

In this paper, the springback and time-dependent springback of 1Cr18Ni9Ti stainless steel tubes subject to bending is explored. Rotary draw bending tests have been carried out and marked time-dependent springback has been observed. A novel model in which time-dependent springback is associated with strain hardening is presented as an attempt to analyze this behavior. Using this model, the formulae of time-dependent springback, time-independent springback and total springback are derived. In addition, finite element analysis has been performed to investigate the stress distribution as well as to calculate the magnitude of springback. Comparison between analytical and experimental results shows good agreement.

This paper deals with bending and springback phenomena of a stainless-steel clad aluminum sheet in V-shaped air bending. The aim of this study is to investigate the bending characteristics such as sheet thickness change and the bending angles of the sheet before/after springback. The first part of t

In this investigation, the attention is focused on the springback and fracture of thick stainless steel sheets. Nine different stainless grades and various thicknesses are tested. The thinnest sheet is 7.9 mm, whilst the thickest sheet is 31.3 mm. A consistent analytical model is constructed for pre
