“…Cyclic material models were adopted. One can find numerous solutions based on the assumption that the radial stress vanishes in the literature, for example [25][26][27][28][29][30]. Paper [31] introduced a new methodology for springback prediction and then used it to analyze the cyclic bending process.…”

Finite plastic bending attracts researchers’ attention due to its importance for identifying material properties and frequent occurrence in sheet metal forming processes. The present review contains theoretical and experimental parts. The theoretical part is restricted to analytic and semi-analytic solutions for pure bending and bending under tension. The experimental part mainly focuses on four-point bending, though other bending tests and processes are also outlined.

“…According to the combination of the bending moment and axial force, the distribution of stress (expressed by d i and r i ) can be found from equations (3), (5), (8) or (9). F or the ith segment, the curvature, k i , and the strain of the central axis, e i , can be expressed as equations (10) and (11).…”

“…F or an elastic-perfectly plastic material under plane stress condition, Yu and Johnson [8] obtained the change in non-dimensional curvature with the presence of axial force. El-D omiaty and Shabaik [9] extended their work to elastoplastic, nonlinear work-hardening material. A systematic treatment of the axial force effect on the plastic bending is given by Yu and Zhang [10].…”

This paper concerns the large de ection of elastoplastic, non-linear strain-hardening cantilevers of rectangular cross-section, for which the stress-strain relationship after yielding is described by s K 1 e q . Both the bending moment and axial force are included in the yielding criterion, and the corresponding strain increments obey the associated normality rule. Comparisons between the experimental data and the theoretical predictions are made for mild steel cantilevers subjected to a tip force with an inclined angle f 67 5, 90 and 1578 respectively. R easonable agreement is obtained. The theoretical analysis has described the large de ection behaviour of the cantilever and is in good agreement with tests.

“…In the present work, a material property model is introduced and is combined with a previously developed process model for stretch bending processes [1,2]. Because of the complex nature of the process, a common procedure is to rely on the traditional trial-and-error-method for eliminating specific forming problems such as residual stresses and springback.…”

Today's sheet-metal forming industry relies mostly on experience-based methods for finding the forming limits which assure successful forming processes. Such methods are inefficient and there is an obvious need for cost-effective knowledge-based computer-aided techniques.In this paper, a mathematical model for the stretch-bending processes is introduced. The model is capable of performing all calculations necessary to determine the effect of material properties on the process parameters such as forming loads, product geometry, springback, and residual stresses. From this model, the signifcance of various material parameters from productivity, ease of fabrication, and tool design viewpoints can be evaluated. This should contribute to the development and optimum use of sheet materials with improved properties.
