Journal ArticleDOI
Numerical results from large deflection beam and frame problems analysed by means of elliptic integrals
TL;DR: In this paper, numerical evaluations of elliptic integral solutions of some large deflection beam and frame problems are presented in tabular form with up to six significant figures, and the numerical technique used for evaluating the elliptic integrals is described.
Journal ArticleDOI
On constitutive modeling for springback analysis
TL;DR: In this paper, the influence of constitutive modeling for springback simulations is analyzed for four different materials in the rolling-, transverse, and diagonal directions of a simple U-bend.
Journal ArticleDOI
On the modelling of the bending–unbending behaviour for accurate springback predictions
TL;DR: In this article, the springback of a simple U-bend has been calculated for one of the materials, and from the results of these simulations some conclusions regarding the choice of hardening law are drawn.
Journal ArticleDOI
A viscous pressure bulge test for the determination of a plastic hardening curve and equibiaxial material data
TL;DR: In this article, a Viscous Pressure Bulge (VPB) test is described, which yields the equibiaxial stress point and r-value, as well as a plastic hardening curve for large values of plastic strain.
Journal ArticleDOI
On the identification of kinematic hardening material parameters for accurate springback predictions
TL;DR: In this article, the authors tried to understand the background of these differences, to find out the influence on predicted springback, and to determine which of the two methodologies for hardening parameter identification is the most suitable one.
