characterization of the strain induced plastic anisotropy of Rolled sheets by using sequences of simple shear and uniaxial tensile tests
Journal of Materials Processing Technology, 2006Co-Authors: S Bouvier, H Haddadi, B Gardey, Cristian TeodosiuAbstract:Abstract The characterization of the plastic behaviour of Rolled Metal sheets at large strains is a critical ingredient of any finite element analyse software aimed at predicting stress and strain distributions and the eventual occurrence of defects in sheet Metal forming. On the other hand, due to the reduced thickness of such Rolled sheets, the experimental techniques available for their characterization are scarce. Recently, however, the development of reliable simple shear tests has brought a real breakthrough in this area. The present paper shows how two-stage non-proportional loadings involving sequences of simple shear and/or uniaxial tensile deformations can be adequately used to investigate the isotropic, kinematic and distortional hardening of Rolled Metal sheets at moderate and finite strains. The experimental techniques and their optimization are analysed and several examples concerning currently used structural materials are provided.

simple shear tests experimental techniques and characterization of the plastic anisotropy of Rolled sheets at large strains
Journal of Materials Processing Technology, 2006Co-Authors: S Bouvier, H Haddadi, P Levee, Cristian TeodosiuAbstract:Abstract A detailed analysis of the simple shear experiments on Rolled Metal sheets is undertaken, in view of their optimization. The shear strain and stress heterogeneities eventually due to the free ends effect are investigated, as well as the best way to prevent premature failure, by choosing an adequate shape and clamping of the specimen. Finally, the application of these techniques to various Rolled Metal sheets, illustrates the ability of simple shear experiments to characterize the strain-induced plastic anisotropy both under monotonous and Bauschinger-type loadings. This is particularly relevant for the identification of constitutive models involving large strain isotropic and kinematic hardening.
